I have only one 45acp, a P97dc that I bought a few decades ago. For years it was my primary home defense handgun and has never been anything other than totally reliable with any ammo I fed into it and more accurate than my old eyes are capable of achieving. But after a brief foray in both 40S&W and 380acp I "evolved" into 9mm for both home defense (a Glock 17) and concealed carry (a lc9s). But after not firing the P97 for what has turned out to be about 3 or 4 years, I took it to the range today. Just looking at the cartridges of both the 45acp and the 9mm made the 9mm look awfully puny in comparison. And firing the P97 reminded me of both how much I like this gun and how satisfying it is to fire that big caliber pistol, and do it with confidence and accuracy. And years ago I always thought of the P97 as far too big to use as a carry gun, but today I used an old pocket holster and found that the P97 slid nicely into my jeans pocket and would not at all be a hard gun to carry concealed. I must admit that I am now tempted to put the lc9s away for awhile and start carrying the P97.
