Picked up a LNIB Glock 40 10mm a bit back and gotta say the thing isn't very accurate. It wears a Holosun green dot. Thinking that maybe the new holosun was crap, I took it off, replaced the OEM front sight post with a fiber optic one that is nice and visible, and still it sucks. I got this to change up my handgun hunting from TC's and revolvers, but I couldn't ethically take this thing afield. Now, it doesn't have a nice trigger like my Contenders and revolvers, but still.....I shoot/own plenty of other glocks, but from a solid bench rest, I can maybe put two rounds about 4" apart, then another two a foot and a half away on the other side of the target at 50yds. For kicks and grins, I shot my G19 from the same rest at the same target, and manged a 4" group. I'm not going to the olympics or anything, but acceptable game accuracy is a must. That, to me, is 4-6" at 100, which even with my worst pistol I can manage easily.
However, I'm new to 10mm, and started to reload it. I understand the manuals really reduce the 10mm's potential. (what I've heard) I'm running a 180gr over a published max load of 231 (don't have the details right in front of me right now) So, does the 10mm like hotter, full power loads? Do Glock 40's prefer heavier loads? In all my years of reloading, very rarely do I produce a load thats unacceptable in a handgun. Sure some are better than others but they're always acceptable accuracy wise. So, I don't think my load is causing 1.5ft groups. I'm looking at some 165's over AA No9 for 1,400fps. I did try some factory fodder, just one box, and it didn't perform much better. I've never owned a Glock that didn't perform as intended, so its got me stumped. I don't want to throw good money after bad but i'd be willing to put a KKM barrel on it, see if that makes a difference. I guess my basic questions are 1. does 10mm perform like shit when loaded down, and does the G40 not like these light loads.
When I say light loads, most 10mm data i've seen isn't that far off of 40 S&W,
