    Sub compact 9mm ammo weights?

    In a 3.5" or 3" barrel 9mm like a GLOCK 26 and Kahr PM9 is a light fast bullet better like Corbon's 90 grain or 115 grani +P load or is a slower heavy load better like a Premium JHP 147 grain. Or the middle ground 124 grain JHP. I shoot 115 WWB exclusively for practice but find 124 Fed Hydras are dead on out of my GLOCK 26. But I will be getting a Kahr PM9 for ccw and am looking for the best load in terms of terminal ballistics and accuracy of of the little PM9. Is the accuracy based on a gun by gun basis or is it pretty general for barrel length?

    I typically find that the smaller the gun's barrel length the closer in you need to be. As you are shooting center of mass, and as the 21 foot rule usually applies in defensive situations, I personally don't think bullet weight is going to matter much. Just my $0.02 worth. Some folks agonize over ballistics and for hunting that probably is a good thing. I may be wrong but I just don't worry too much about it. I load my Kahr P9 with a good, reliable JHP ammo.

    From my tests thru the R9 - so we are talking real short barrel, just over 2 1/2" - I found relatively minimal difference between 115, 124 or 147 at combat ranges. I am in effect saying same as Joe.

    I carry 124's in that and also SIG - and as a compromize reckon they do good. I would tho try all flavors in your own gun and probably opt to use what works best for you, in said gun.

    out of my glock 26, i've seen maybe a 50fps loss in velocity in 115gr ammo compared to my glock 17 shooting the same stuff. I use HST 147gr as my carry load.

    My Kahrs like midweight bullets like Speer's 124 grain Gold Dots, which is what I carry.

    I was using Federal 124 +P+ HydraShock but my supply went dry after some serious testing I started using Federal 147 HST & 124+P EFMJ and 124 HST in that order. The 147 load really surprised me as for being quite accurate out of my Kahr K9 the 124 loads work but not as accurate as the 147 load. Belive me I tested 1200 rounds of different carry ammo and these 3 were the best for my gun.

    My Kahr PM9 prefers the 124+p Gold dot loaded by Black Hills. Many others such as Hydroshock work well but it hits to POA, is accurate and hits hard (based on many documented cases by LE). It chronoes between 1050FPS and 1090FPS in my PM9.

    As a note, my PM9 does not shoot 147g to point of aim...it shoots them much higher. Ya just have to try em all!

    Good news and bad news. The bad news.....I'm afraid the answer to your question is.....there is no easy answer. Your gun will usually shoot different than my gun with the same ammo, even though your gun and mine are the same make/model. If you agree that shot placement is more important than bullet weight, then you should find the bullet and bullet weight that works best in your gun...... The good news is, you will always have an excuse to go to the range to "test" a type/weight of bullet!

    The first 9mm load i try in any new pistol is the Black hills 115gr
    +P.They use the excellent God dot bullet at 1300fps,muzzle flash is low and it has been accurate in
    every pistol i've tried it in.
