Well, after reading that long ass thread about the Glock vs. the 1911, I have to say I was sold on the Glock by it's owners on this board. I took my POS S&W 4053 to the show on Saturday and sold it to another individual exercising the "Gun Show Loophole," and applied the proceedes to a brand new Glock 22.
I was really up in the air if I should go Glock 23 or 22. The 23 was very easily concealed, but the 22 hid just fine, so I took that one. It is amazing how well it fits in the hand compared to the POS S&W.
On the last thread someone posted that the .40 had superior ballistics to the .45 I disagree with this, while it might be true with the slow 230gr bullet, it does not fly for the 180+P or 165+P loads. Check the velocities and foot pounds on Cor-Bon loads:
.40 135 JHP 1325fps 526ft/lbs
.40 150 JHP 1200fps 480ft/lbs
.40 165 JHP 1150fps 485ft/lbs
.45+P 165 JHP 1250fps 573ft/lbs
.45+P 185 JHP 1150fps 543ft/lbs
.45+P 200 JHP 1050fps 490ft/lbs
AND the .45 will make a much bigger hole. Clearly, the .45 with a lighter bullet kicks the crap out of the .40
But, in my case, I don't think anyone is walking away from my .40 Cor-Bon 150grainer, and the .45 is just a bit too large to conceal if I got the full frame.
Thanks for the advice guys, see my range report for my thoughts AFTER having purchased a Glock.
