best defense ammo for CM40

[DooSPX]

I am looking for the best (most reliable feed w/ short 3" barrel and most stopping power) for my CM40. I have looked at Winchester, Rem., Hornady, Speer, Fed. I see Speer has a round specifically for short barrel sub compact guns...

Thank you

advertisng hype. ore than anything. find a round that u like that works perfect and ur gonna notice no difference IMO. a fotay in a kahr is a handful and the power of the round should bemore than enough. RELIABILITY HAS TOBE #1. That short barreld speer round certainly does not outsell the standard +P speer gold dot, which most surverys show that it is the round of choice. It ahs been around for years, so that in itself should tellu sumpin. I am found of corbon powerball as it fees just like a fmj round. It is not a speer gold dot but damn close and it probably would be towards the bottom of most people carry round. Not to sure if one caqn beat the corbon DPX round as the best of the best to

I'm a Gold Dot man, but CorBon PDX ain't bad. Make sure that it feeds well in your pistol. See the video.

If I were you, I would give serious consideration to the Speer short barrel loading for your CM40.

I am for my G27.

Speer lists the 180 gr. GDHP @ 950 fps out of a 3.5" bbl. with 361 ft. lbs. of energy at the muzzle.

FWIW, my current SD load in my G27 is the Win. Bonded 180 gr. JHP PDX1.
Great load in the G27, very accurate with managable recoil to be sure.

didnt notice any significant advantage to the "short barrel" .40 vs a regular 180gr jhp. (we were shooting a glock27) Any good quality 180gr .40 defense round should be ok. I would just avoid the lighter loads in the short barrel.
then again, excuse for some range tests because ITS PUMPKIN SEASON!!!

I have a friend who can get Winchester Ranger T 180gr. I rather have that then the PDX1. Who has shot 180gr from their CM/PM 40 cal. Kahr's? My target rounds are only 165gr.

I have a CM40 that jams when feeding. Its been sent back once, but still jams when feeding from the magazine. It was recommended I try .40 Winchester T-Series 165 grain. Anyone have suggestion or comments that might help me beat this issue? Love my Kahr, but until I find ammo that won't jam when feeding, I'll just carry my 9mm Sig Sauer P365. Thanks so much.

Just wondering if you notice a difference in accuracy in addition to the jamming. My CW40 (bought new) would jam constantly (especially FMJ). I sent it back to Kahr, and the issue seems to be... better? Now the jams are rare, but I can feel that the slide is meeting some unusual resistance when returning to battery to fire the next round. After the warranty work, I've only tried WWB JHP and Hornady Critical Defense, but they both seemed to work OK... considering I had only one failure to return to battery through the few boxes of those two brands I tried. Additionally, while my other Kahrs (including calibers 9mm, 40 S&W, and 45) are very accurate, my CW40 groups larger (offhand). It was really bad before the warranty work... now it is better. Insterestingly enough, my T40 is both reliable and accurate. I, too, have placed the CW40 in the "needs more range time" to get a better idea if there is still an issue and whether to send it back for additional work. I know some people here have suggested that their CW40 was more accurate/reliable than their other Kahrs, but I haven't had that experience. I have had good experience with my other Kahr's, so I would really like to get this issue fixed. However, with the limited availablity of ammo in my area, I won't be revisiting this for awhile. Meanwhile, the only issues I've had with my other Kahr's is that the 45's won't feed Corbon ammo.

SD ammo in general, any caliber or weight, I favor;
Winchester Ranger T-Series, Speer GDHP or Federal HST.
In 40 any weight will serve you well.
Being proficient is more important than paper ballistic stopping power to me.
The important aspect is making sure the gun is reliable and hits point of aim with that round.

As for my personal preference in 40, I favor the middle weights 155/165 gr.

My MK40 Elite is usually loaded with Speer GDHP 155.
As they have been chronographed at ~1150 fps 450 E from a 3.0" barrel.
It's one of the hottest 3.0" barrel rounds I've seen.

In full size 40,
my Heckler and Koch P30 is loaded with Winchester Ranger T-Series 165 gr.
I understand the 165 gr Ranger Ts and GDHP have outstanding track records with LE.

Full Disclosure.
Although I have no evidence to support this.
Winchester Ranger T-Series seem to have a smaller, more rounded,
HP nose that may facilitate feeding.
They seem to be the most reliable feeding of the three brands in my various guns.

I've switched most of my carry ammo to Winchester Ranger T-Series;
230 gr .45 ACP, 165 gr 40 S&W, and 125 gr 357 Sig.

I'd have to agree with Barth when it comes to choices of brands of ammo. From the videos I've seen with these rounds in ballistics gel. Gold dots, Ranger Ts, and HSTs all seem to expand the best with the petals seeming to cause the most damage while traveling through the media.

As far as weight goes, can't speak too much to that. I'd recommend checking out TNoutdoors9 on youtube. He has some good videos on testing .40 ammo. I do however have a mag of Federal HST 180 grain loaded for my XD in case a situation arises where I'd need to defend myself at home, and I have confidence this round will do the job just fine.
