Defensive rounds?...CM9

[Athensm50]

So I and thru the break in period.....YEA!!!....:D.......and I now will start my quest for a Defensive round to run in my CM9.

I have shot WWB(Winchester White Box) thru my XD9 for years......Not sure how they will shoot thru the Kahr???.....

so this leads to 2 questions:

1. I hear a LOT of thrash talk against the WWB rounds....Why?......I have shot them for years....everytime a have pulled the trigger they go bang???

and

2. What are you Carrying?....What runs best in you Kahr?

Thanks!

i read this and took his (and a leo friends) advice. i run the 147gr winchester rangerT's or the 147gr winchester pdx's. i have never had an issue with them and they preformed best with some tests we did with different ammo. (the pdx is what the feds use)
"When we redesigned the Ranger T Series of ammunition we widened the velocity window under which the round would expand to allow for the slower velocities that shorter than standard barrels produce. What this means is that if you own a standard or sub compact pistol the round should have adequate expansion. In 9mm I would recommend the 147 grain bullet as it loses a lower velocity percentage than the faster lighter bullet in shorter than normal barrels. This is because the bullet has more dwell time in the bore and has a greater opportunity to burn the powder before the bullet exits the bore. Powder that is burned outside the bore does nothing for velocity. The lighter faster bullets generally have more powder to burn and since the lighter faster bullets have less time in the bore they are not efficient burners of powder in the shorter barrels.
We increased the velocity window under which the round would expand by increasing the size of the hollowpoint, tweaking the jacket thickness and the depth of the cuts on the inside of the jacket petal segments.

For what it's worth, my CM9 works well with the Winchester Supreme Elite 9mm 124 gr (+P) PDX1 bonded JHP round and that is what I use for CCW.

[Thunder71]

Ballistics don't mean squat if a round doesn't chamber, that's why I go with what feeds and goes 'boom' every time in my guns - Winchester PDX1 Bonded.

[Bill K]

Lots of good 9mm SD ammo you could wade through. What Thunder71 said about feeding and going boom every time is of primary importance. In a relatively light gun like the CM9 felt recoil/muzzle flip might guide you to one reliable ammo choice versus a another.

[LonghornFan69]

I guess I am going to give it a try if I can find it locally.

[Thunder71]

Our Walmart carries it, that's another high point for me - easy availability.

[Rubb]

I’ve tried others and always come back to Gold Dots.
In the past 15 years they have consistently been on the top of any list I’ve seen.

[rogerthedodger]

In my 9 MM guns it's Speer Gold dot +P 124GR GDHP short barrel
or
Hornady CD
Roger

[ctrcs]

I shoot Hornady Critical Defense 124 gr. in mine. I have also shot the Speer Gold Dot Short barrel effectively. The PDX1 124 +P were noticeably snappier and harder to double tap with.

[JimC]

Speer 124 gr. +P GDHP short bbl. for my PM9.

[joe d]

Speer 124 gr. +P GDHP short bbl. for my PM9.

+1 on the Gold Dots..

[LonghornFan69]

Our Walmart carries it, that's another high point for me - easy availability.

My Wal-Mart is always out of ammo in 9mm, they don't keep it stocked very well.

[JFootin]

I'm going to try some standard pressure 147 grain HPs.

[evnash]

my local shop has a 250 round box of Gold dots for $99. yeah they blemished from the factory but all they have are nicks on the brass.

[JimC]

I'm going to try some standard pressure 147 grain HPs.

Give the Winchester Ranger Bonded (RA9B) 147 gr. load a try.

I can't speak to the expansion of the bullet but they feed 100% in my PM9 and the accuracy is very good.

[cesande]

Hard to find but I know a couple of years back HST was king.
I still have some Federal HST 124+p that will get tried out in my Kahr 9mm when I get one.

[Thunder71]

I've tried HST, Gold Dot, Critical Defense and many more - they all nose dive hard when hand racking my PM9, anything Winchester is smooth as butter.

[pocket pistol]

I got through my break-in period last weekend. Then I ran about 18 rounds of Federal HST without a hiccup. So my CM9 is presently loaded with Federal HST. Plus you get 50 rounds for like $25. It's that much for 20 rounds of the other premium stuff.

[Athensm50]

That was kind of mine question to begin this....I have shot WWB for years out of my XD9.....like the Federal HST....they are cheaper that the primo stuff.....

are they that different?.....will they not expand?.....Like Pocket Pistol said....WWB...about $25 for 50 rounds.

[wyntrout]

Same as Roger. The PDX1 .40 S&W had the lowest flashes in my limited testing, though.

AthensIf I could consistently find them and afford them, I'd shoot Federal HST 135 gr +P. Having said that, you lose so very very little (in short barrels) going to standard pressure 124 gr, I shoot those in Federal HST. My #2 choice is Speer Gold Dot 115 or 124gr. Next on my list is Winchester PDX1

[JimC]

IMO, when it comes to personal protection ammo, the cost is irrelevant as long as function in ones own pistol is 100% and if that means paying premium price, so be it.

I agree, but then I admit I'm not very perceptive on this kind of thing.

I've tried a couple of different brands including Federal HST and the Winchesters, and I really can't tell any difference. They all seem the same to me: they go bang and they hit the target. That's all I really need.

I keep reading various tests that show some small measured differences in velocity, size of cavity created, etc, but I can't really translate that into anything but numbers and theory.

Debate over this reminds me of the endless debates about wine: which vintage is supposedly better than the other, etc, and where people are strangely willing to pay huge premiums for a variety that is somehow infinitesimally "superior" to similar items. I can sometimes tell the difference, but am happy that I am very satisfied without needing to spend $$$ on the very best.

And I keep telling myself that I wouldn't appreciate a Wilson, either. :)

[JimC]

And I keep telling myself that I wouldn't appreciate a Wilson, either. :)

I had a Wilson CQB and liked it a lot. I guess I actually appreciated it at the time however, I really appreciate and like my Ed Brown Kobra Carry and still have that one. :D

The cost of the best personal protection ammo for your pistol is a very small part of the cost factor when one considers how much the pistol cost.

[Athensm50]

ok...so I found a vid. on You Tube....this guy does LOTS of ammo testing....this answers my question about the WWB.....he even does another vid....he gives link at end of Vid. 1

[muggsy]

Another vote for Speer Gold Dot 124 gr HP. Don't care for the +P version in a short barreled gun.

[ponycarman]

Anyone have a video comparing the recoil of the cm9 with +p loads vs standard pressure?

Undoubtedly.

I did a poll a while back on this board to find out if people spent more on guns or on ammo http://kahrtalk.com/showthread.php?t=10597 and 63% of respondents said they spent more on guns, which further bears out your assertion.

I am definitely in the "more guns than ammo" category, by a long way. It seems a lot more exciting to buy a nice guy than a box of bullets, but I'm slowly getting with the program now.

[chrisw670]

I carry Remington Golden Saber 124 gr. +p in my CM9. So far, they've run flawlessly through the pistol. I'd love to find some Corbon DPX 115 gr +P but haven't had in luck locally.

[MichaelK1950]

So far I have shop Gold dot's, Horniday Critical Defense, Double Tap, Buffalo Bore JHP and have had no problems at all feeding or ejecting. I just got some Golden Sabre but have not shot them yet. In the 600 rounds thru my CM9, I have had no ammo problems at all.

[qwikrex]

I've always carried Speer gold dot 147 gr. in my Glock 19. I carried it for a bit in my CM9, but I've since switched to gold dot 124 gr. +P short barrel due to the shorter 3" barrel on the kahr. Although both shot well through it.

nope, but the recoil isnt significantly different... i shot mant different loads through my pm9 and the standard 147gr was the most effective at dismantling pumpkins, water jugs, and definitely appeared to transfer the most energy during vest tests with the pm9. the lighter rounds are out of the barrel before all the powder is burned.
all the diff rounds i fired felt about the same. not enough diff to let it effect your decision but worth trying.

[Simms65]

GDHP 124+p for me. It is what I stock for my other pistols and it works 100% in everything I've tried it in.

Awesome thanks for the info. Right now I have critical defense in it. Probably just leave it in. Then get some +p for my glock 17.

I carry HST +P 147gn in my PM9 and they feed every time. You can usually find them at Kyle's Gunshop, Inc. (http://www.kylesgunshop.com/)
