DO IT! I did and I've never regretted it. I tossed it around for quite awhile. Do I or don't I? If I do which one? I finally bought a Rock Island full size double stack 1911. Yes it's a beast. I'm am of average size including my hands and this double stack feels great! I had already decided that that this was not ever going to be an every day or even an occasional concealed carry gun but that was pretty obvious. Well guess what. I can slide this horse into a Galco open top slotted belt slide holster at around the 5 o'clock position,throw a tee shirt over it and no one would ever know I had it on. Seriously! Not to mention that it is extremely comfortable. Standing, sitting makes no difference. It defies all the expectations and rules or laws or whatever of concealed carry. I was carrying a S&W M&P 2.0 3.5" .40 in a kydex IWB and it was great. In fact I still carry it on occasion. It's not as comfortable to carry as my 10mm. Now as far as shooting the gun. I like it!! Maybe a slight more recoil than a .45acp but it just feels really good. Ammunition is not cheap but when did that ever stop us. No ammo is cheap nowadays.I'm thinking about getting into the 10mm game, but I don't know much about it. I've never owned one before, but I'm thinking that I might. If'n I do, vhances are it'll be a gen4 Glock 20 or 29.
