Most of my 9mm handguns prefer 147 gr FMJs for practice (or maybe it's just the way I shoot?). The lighter bullets, especially the 115 gr ones seem to print quite a bit under the point of aim, maybe 8-10 inches in those guns. I found that using the heavier bullets my point of impact was closer to my point of aim. I am speaking of ranges around 20-25 feet, which is as far as I'm ever likely to fire this pistol.
I have not shot the CM9 yet, but plan to burn up some Blazer Brass 115 gr FMJs as I work toward that recommended 200 round count. Any particular load I ought to try to avoid? I heard somewhere that the CM9 isn't too picky, and many folks just Winchester's 9mm "white box" ammo. I never use steel cased ammo, but I have used aluminum cased ammo without incident in many other pistols.
Also, regarding carry loads; what is the consensus? Any bullet type that the Kahr CM9 does NOT like? My usual carry load is Speer Gold Dot 147 gr JHP. But I also occasionally carry Federal's Hydr-Skok in 124 and 147 gr. Suggestions are always welcome!
