View Full Version : Part II TP45 Covert project

My new TP45 came home on Wednesday. I intend to shoot it a bit before I start my transition project to convert it into a “Covert” model TP45. So for now this is a routine range report for anyone interested in the big Kahr.

I’m a true believer in the product Militec-1, so the gun got a good cleaning and is now fairly wet with a coating of oil. I didn’t do a hairdryer heat treatment because I will be shooting enough to get the metal hot… a requirement for the Militec-1 conditioner.

Another phase of my usual pre-shooting regimen is to clean the mag tubes and mag springs with Eezox, another product that delivers useful qualities, namely a slick, dry, rust-inhibitive film. All of my mags see Eezox.

I have a fairly good supply of .45acp ammo, so I’ll be able to initially test some 230 gr. FMJ from Winchester, Blazer Brass, Remington, American Eagle and two HPs by Gold Dot, Hornady TAP +P, and some Magtech 165gr SCHP +P, (a round I’ve previously had some feed problems with).

Just returned from the range, here's the result...

http://i72.photobucket.com/albums/i186/ripley16/Pistols/Kahr/TP45010.jpg

I shot a total 149 rounds of all the ammo mentioned. The Magtech once again failed to feed. It is a round to be avoided at all costs.

The center green dot was the very first 5 round mag shot solely to get the "feel" of the gun. The six green dots are ten round groups shot to see how the rounds fed, felt, grouped, etc. Starting at 12:00 and going clockwise, I shot Winchester,Remington, Hornady, Gold Dot, Blazer and finally American Eagle. The Target at 7:00 was originally Magtech, but I only fired one round, (circled), and gave up on it and shot 5 rounds of Blazer. These were all shot at 7 yards.

The two Orange Peel targets were used to test the speed of rapid fire, unaimed shots with a full mag +1. This was a mixed bag as I am pleased with how the gun shot, but I had a couple malfunctions. These were shot at 3 yards.

Not counting the worthless Magtech, I had the following problems;
* Slide lock on 3 rd. of a mag... may be me as I shoot thumbs forward and tight to the slide.
* Three stovepipes, all three with a very deformed case. One was hard to clear as it also jammed into the mag. All were on the last round.

I fired one magazine with my left hand, unsupported and was surprized at the recoil. My left hand is evidently much weaker than my right. I'm able to hit what I see, but it kicks hard. Single handed shooting with my right hand was much easier.

As you can see the vast majority of my shots were low and left. I think the sights are off a little bit, but I admit I tend to shoot there usually, just not that consistently.:rolleyes:

I might go ahead and shoot another hundred or so before I do any cutting. If the gun isn't reliable I wont adulterate the gun. I'm hoping it will smooth out and lose the stovepipes. We'll see...:confused:

I've never had that Mag-tech fail to feed. In fact it is my load for my P45, and my reloads for my P345. I agree though you need some more trigger time with that pistol though.

Seems to be close for elevation, just off to the left. If you think your working the trigger right and not milking a little sight adjustment might be the cure. I like the tight little Gold Dot group. The TAP seemed to be right in there and not as far left either?
I believe it will straighten itself out.
Was it the same magazine on all 3 stovepipes? Same ammo or a mix?

Ripley, I would have guessed that you were right-handed because your groupings are to the left and low, as mine were with the PM9. I couldn't improve much on that even knowing what I was doing wrong. After I got the PM45, things changed and I was hitting or around the bull and not to the left anymore... the same with the P380 when I got that. When I went back and tried the "stepchild" PM9 again, I shot it about the same as the PM45 and P380. It's really about the trigger pull and control during the pull. I'm not saying that moving the sight wouldn't help now, but you might have to move it back before too long.

And when you start your project, you might consider modifying the grip around, say a 6-shot 1911 mag that works with the slide lock. Some of those mags work quite well and are flush fitting. There was at least one person who did that and even cut a recess in the front of the grip to make the front "tab" of the base fit flush. I think that he cut down a bit and re-welded the base on the 1911 mag, though.

The reason I think the sights are a bit off is because all but two of my aimed shots are too the left. That's very unusual. I'll take a look at the sights after I clean the gun to see if there's anything obvious. Being a bit low could well be a trigger finger problem. This is the least smooth trigger of any Kahr I've ever fired.

One thing I forgot to mention in my first post is that I developed a small blister on the back of my thumb. I don't recall any gun ever doing that before. Maybe I'm getting soft in my old age.

Are you carrying the 165gr solid copper rounds?

This is the third pistol I've had that will not feed, (ie; go to battery fully) this round. In addition to not going to battery, the round jambs in so tight is is almost impossible to retract the slide and unload the stuck round. I ended up smacking the rear of the slide to force the slide home and then shot.

I tried to give the ammo away at the range and had no takers.

Other MagTech ammo has not given me this problem... only the solid copper bullets give me problems.

The small blister is where my thumb joins the web and rests on the left side of the beavertail. I guess the gun was rubbing there too much. Except for the 60 slow fire rounds, the rest, 89 rounds, were rapid fire, about half of it +P and the tiny grip moves in my hand a bit. You'll notice I've added a grip sleeve. Usually these help.

Could that be from the magazine release? I have no problem with the slide release, but that mag release button on the .45 can wear on your thumb after a while. It's hard for me to stay off it. That sucker could use a little "melting", but I've go the DLC finish.

Okay, the web... yeah those nibs bite. My tube helps, but if you already have a sore place, it just gets worse.

This is one project I had confused with a covert modification, I think. I just misplaced another link, dang it.

Gotcha, the coursness of the grip, not slide bite or rub from a high grip hold although the high grip hold would contribute to the blister in that area. I knocked some of the rough off on my PM and did the tube deal or I'm sure my hands would have been hamburger helper for sure.

I carry the solid copper hollow points, I've fired a pretty fair number, and haven't had a problem one. They shoot a hair low, but that's the difference in bullet weight. How old are those rounds? Perhaps they have swollen a bit. It's the same thing as the Corbon DPX round, and a couple of others that use a Barnes X bullet. Being solid copper, they rounds might swell a bit if exposed to certain chemicals and/or humidity. I'm just taking a stab in the dark on that one.

The TAP is the ammo I carry in my CCW because I've always had excellent, consistent accuracy from it and Gold Dot. TAP is the benchmark by which I measure other brands. Seeing the TAP off so far is the main factor that makes me think the sight is off a tad bit.

I don't know which mags were which. I was alternating them only to use them equally. The stovepipes happened with Remington, Blazer Brass andGold Dot. :eek: ...all fired fast, at a two or three rounds per second rate.

I had problems from the day I bought them, 100 rounds total. I have only about 15 rounds left, but I'll not try to shoot them. Bad batch maybe. If we lived close to each other I'd give them to you.

Could be the bullet isn't setback as far as it should. The bullet gets stuck in the bore and simply will not seat properly. I bought them originally to shoot in my HK, but they didn't work. Tried them in my P45 and they didn't work.

Trip two to the range

Fired another 59 rounds of mixed ammo. At least now I'm over the 200 round "break-in" period. I had one more stovepipe, this one in the middle of a magazine, not the last round. I still shot poorly but this time I took another gun that I always shoot well with...just as a control against which to measure myself. The truth is I shot both badly... no excuses, just a bad week at the range. I did manage one really good group.

The misfeeds are troubling though. Here's a picture of some of the crumpled cases. Four cases a problem, two others ejected without causing a stopage.

I'm having some serious second thoughts about this pistol ever being a CCW. 4 stovepipes out of 208 rounds is a lousy record. :ohmy:

The first mag opened up my blister too. At least this time I took my shooting glove. :cool:

These rounds ejected looking like this? Didn't get run over by a derelict in a wheelchair or stepped on? Reread, 4 jammed the gun up stovepipe. Those are really messed up! The two that made it out without stopping the gun don't look so hot either. Are all the ejected cases buggered up?
I just gotta ask too, what the heck are they setting on for the picture. Guess # 1 a furnace filter? It's a great background.

ripley, although kahr brass ejections willbe somewhat deformed, YOUR IS TOTALLY not right. Your gonna get some issues with brass looking like that. What I would do is call kahr and talk to IAN and see if they will pick the gun up and for damn sure include the brass you pictured here or at least a photo.

that to me is just not right. It looks more like Bawanna's wheel chair marks than ejection marks.

IMO, it needs to go back to get your confidence back. One would have a hell of a time resizing that brass

Actually one of the really trashed cases made it out OK, and one of the not-so-bad cases caused a stovepipe. There may have been others. I didn't look at all the brass.

My photo background is a piece of black felt (and a fair amount of cat hair I see).

I'll shoot a bit more, see what happens, but a return to Kahr may indeed be the solution.

Just out of curiosity are there any marks on the back of the cases around the primer? Ejector dings, primers don't look all flattened out or anything out of the ordinary. I think Jocko's correct in that those will fair poorly in the resizing die. I've seen brass driven over by cars at our dept range that looked way better than those.
For sure let us know what Kahr says if you end up contacting them, I'm real curious what could mangle the cases that bad. I just sorted and inspected the couple hundred cases I shot thru my PM45 the first trip and there wasn't a single ruined one in the bunch.
Has to be an extractor, with 4 stovepipes in 208 rounds, the ejector is kicking them out, the extractor might be slippin or not grabbing as positively as it should. Now I'm genuinely perplexed.

Anyone else agree with me when I recommend not recommending a solution for gun repairs, car repairs or even doctors. Seems you make a suggestion and they get hung up on what you recommended and sometimes miss the real issue. I know I go to the doctor and tell em my finger hurts and they want a complete history of why I came in in a wheelchair.???????? Your fingers broken duh?
Describe the symptoms, and play dumb and let them finger it out.

Other than an expected slight mark from the extractor, no the cases are not otherwisw marked or dinged.


... I'm real curious what could mangle the cases that bad. I just sorted and inspected the couple hundred cases I shot thru my PM45 the first trip and there wasn't a single ruined one in the bunch.

Primarily it was the slide closing down on the case that crushed them, 3 of the four were the last round...these are the ones that were mutilated badly.


Has to be an extractor, with 4 stovepipes in 208 rounds, the ejector is kicking them out, the extractor might be slippin or not grabbing as positively as it should. Now I'm genuinely perplexed.

The extractor appears to be in fine shape. The ejector looks like all other Kahr ejectors, so I'm perplexed as well. I see Goofa ran a similar number of rounds through his new TP45, bought from the same place at the same time is causing him no problems.

I have a bum shoulder I hurt a week ago while cutting down a tree. I'm wondering if it is affecting my shooting. I couldn't shoot my T9 either and that is one gun I've always shot well with. I'll shoot again after I've mended a bit more. I'll report back on this one in a week or so.

Thanks for all the advice.

Ripley,

I got that same blister the very first time I shot my PM45.
I also shot something like 235 rds that first time out.
It was definitely the beavertail rubbing as the gun recoiled
up and the left as I shot. I haven't put that many rounds through
the PM45 in a single session since then so it hasn't come back.

Are you still planning the Covert project on your TP45? I'd be
real interested to see how it turns out.

Best of luck!

That's covert... easier to carry concealed... with a longer barrel and maybe more capacity. I think he meant to shorten the grip a bit to make it easier to conceal.

No. This looked like a great idea "on paper", but in the flesh, both the malfuctions and the fact that I really didn't take to the gun brought me to the conclusion that I didn't want to continue.

This may be a great plan for some other person, but the very light weight TP45 just wasn't my cup of tea. Maybe if I were a bit younger.;)

WOW, sorry. I have had great experience with my P-45, Better acceracy than 4" colts. Much lighter. Is "covert" a factory option?? Gun store in my area has a long slide 40 with short grip and polygon rifling. Having store guy come to the range and will compare to my PM40.
On ejector problems, had the same thing with my S&W 52-2. Turned out it was a ammo, Selliro & belloit, problem, tried it in friends 53-2 and he had same problem, no problems with hand loads or other factory.
Sorry to hear your plight, I was mulling over a larger Kahr 45.
Was going to replace my PM40 with PM 45, still like 45ACP. BUT, PM40 is a shooter, with CTL 1" groups at 50 or less feet rapid, that is less than 3 seconds after somee one else yells go!
