9mm Defense Ammo

[skiumah]

I use some Hornady TAP FPD and have never had a feed issue with them in my Kahr.

[Jeff00042]

Hornady TAP FPD is super accurate with no failures in my PM9.

[AIRret]

I use federal HST. I've never had a feed problem and HST is what our local police use.

[almalave]

I use Critical Defense with no problems at all. Shot a couple of mags with +P HST without a hiccup but noticeable recoil increase. I'll stick with the Critical Defense though.

Ok, call me a noob, but isnt 8 inches of penetration (guard dog) pretty decent considering 8 inches into a BG would hit vital stuff right? I mean you lose the "cutting edges" but you dont run the risk of a clogged hollow point injuring someone else right?

Hmm. I was just getting ready to go out and get something to replace the Guard Dogs in my Sig.....

I like the way Ranger T 147 and HST 147 run through my CM9. Also, both have shown excellent expansion and penetration in a multitude of tests. They can be hard to find though.

personally i shoot 124 +p gold dots. there's a local reloader, RAM ammunition who loads up gold dots and sells boxes of 50 for 18 bucks at the gun shows, so it's cheap enough i can afford to train with it. i know, gun show ammo for defensive purposes is iffy... but when you can afford to shoot (and do) thousands of rounds of it, you get to trust it. i've never had any issues with it after roughly 20k rounds.

the gold dots he sells aren't reloaded, he uses new brass for them and the same bullets as speer gold dots. he just packs them himself and sells them cheaper.

his reloaded stuff is 9 bucks for 50.

[GROTMAN]

Also using and recommend hornady critical defense.

NOOOB!!!!!

Just kidding. It's a reasonable question.

8" of penetration for a face to face midsection hit, on a stationary target, without contacting any bones or other barriers will likely go into the vitals of a normal human.

It is unlikely the target will present themselves in such a manner. I'm a relatively skinny dude, and my chest is about 10" deep, 12" collarbone to sternum, and 15" side to side. Throw in a few ice creams and big macs, or perhaps weekly weightlifting, and that could go up 3 or 4 inches pretty easily.

In other words, if you consider the likely scenario of angled trajectories, bones, fat or muscular antagonists, heavy clothing, etc most "studies" suggest that about 12" of penetration is pretty good for most situations.

Looking for some recommendations for defense ammo for my CM9?

Have you seen these test results I did a while back with PM9s and K9s?

After the 1986 FBI shootout in Miami Dade county(look it up on Google) . The FBI went looking for a different caliber and certain criteria. One of them was penetration which was the most important to them. I seem to remember they wanted a minimum of 11" and a maximum of 18" penetration.
I did some wet pak test here and the penetration results aren't the true results, you need to use a formula that I forgot, to convert them to ballistic gelatin results that the FBI uses. I know that the true results of my tests are acceptable

Anyone try these? For $17.50 per 50 rounds I've stocked up quite a few. At 1300 fps they are sneaking up on .40 S&W without near the snap. Not that you should shoot them all day long but when it counts the numbers are there.

Really, with modern bullet design any JHP that feeds and goes bang 100% of the time will do the trick. Pick one you like and run a couple of boxes through your particular gun to make sure they get along and you're gtg.

Velocity is NOT effectiveness. .45 cal 230 grain have a fps of about 900 and no one doubts their effectiveness. These Federals are very light weight bullets. In general heavier bullets penetrate further, faster lighter bullets cause more cavitation, but can be deflected by density like a bone. My feeling is that 124 grain bullets are a nice compromise for 9mm although I like some of the 147 grain JHPs.
