Suppose I want to get rid of my only striker fired pistol, a S&W SD9 VE, so as to purge my gun collection of striker fired guns. What then should I replace it with, presumably in 9mm. I also would prefer to avoid plastic and prefer without a manual thumb safety (except in 1911s). Would a double stack 9mm 1911 in the smaller officer size be a good way to go? What is the best caliber for 1911 besides .45 ACP, which I already have. Do they make a 1911 type 9mm, double stack with double action? Would I want something like that? What other options besides a 1911 are there for 9mm that are easy to come by? Should I opt for 10mm, .40 S&W, or other caliber instead if 9mm?
