What do you look for?
Squisher, after I left the department I worked for in Arizona, the issued Beretta 92's to everyone. Big heavy gun, little tiny bullet. When we were allowed to carry what we wished, after having it checked by the department armorer, I carried the S&W 4506. For off duty I carried a strange little pistol called a COP. It was a four-shot .357 magnum that had four barrels that all fired to the same point of aim at about 30 feet. It had no external safeties or anything else to ruin the lines of this little stainless pistol that at first glance looked like an auto. It had an internal striker that rotated 90 degrees for the next shot.. I look for reliability first. If it doesn't go bang every time I pull the trigger, it is of no use to me. I know that just about any quality firearm can shoot better than the person holding it, out of the box, so accuracy is not a big point. I do demand a major caliber. I carry a .45ACP now, with a 180 grain hollow point. I don't care if it looks as ugly as home made soap, if it works every time and has a heavy enough round to stop any possible bad guy, I am happy as a clam at high tide.
