I own an M40 and absolutely love it. We CCW qualified together with a perfect score even with the guy to my left flickin hot brass at my face and arms. My problem is with another pistol...my Steyr is too big to comortably carry so I bought a Kahr PM 40 (.40 cal) that I can hide literally anywhere it's so small. It doesn't like to hand cycle ammo though and it jams and mangles live rounds on their way out of the chamber. I admit I'm a little obsessive compulsive when it comes to checking and rechecking my carry gun and when it's time to unload it I'm always in for a fight. My question is are there deeper seated rounds for those tiny packages that have obliterated tolerances in the interest of keeping the weapon as small as humanly possible? The gun has never jammed when firing (300 rounds so far) it just hates to hand cycle. I use UMC 180 gr JHP in the green box for about 23 bucks from Wal-Mart (my Steyr and Beretta carbine love the stuff!!) and in my opinion the gigantic hollowpoint on that model makes it ideal for defense. I used to carry the WWB JHP in 180 grain, its hollow point was a lot smaller and I saw it over penetrate every single hog I shot, at every distance. I don't really want to spend a dollar a round if all I'm going to do is let the gun chew on them...any experience with this problem out there?
