Say what you want, but the Glock is the weapon that all are compared against, for good reason. They work, and will work in all conditions, the AK of the pistol world, but guess what, accurate, not bullseye accurate, but more accurate than they should be, the .45 acp is the most accurate of the bunch in all configurations. It needs to be part of your " go to, arsenal " I own many pistols that I have no reservation about, but my model 21 is proven , 20 times over " It harvests the smallest game, and has taken 2 white tail deer. SD no problem, I'm not looking to put a human head on my wall, but if it can hit jack rabbits at night at 25 yrds, well it can do SD just fine.
You XD fans, and S&W M&P fans, I have no argument with, I just have not shot them, 1911 users, I have much experience, and own plenty, but for the overall package, pick the Glock. PROVEN. The 1911 you can say is proven, but only with ball ammo, and if that is what you carry, FINE, I have little doubt it will work. The Glock gobbles it all. 90% of my Glock reloads are 185grn, semi wadcutters, never hiccups.
