I have several semi auto pistols including a S&W M&P 22C that is just fun for shooting at the range. I have a Glock 23 Gen 3 (40 cal) that I have owned for over two decades. Thousands of rounds down the pipe, never a jam, only a few rounds that did not fire (ammo issue). Love it, will never sell it, pray it lasts forever. I also have a conversion barrel for it and can shoot 9mm out of it as well so its cheaper for range fun. I/we also have a Glock 42 (wife's) and its good for a pocket rocket if need to dress light in summer but you have to break them in good and practice with them so as not to ride the slide and cause a malfunction or limp wrist it and cause a malfunction (I shoot it fine, my wife has some operator induced errors at times she prefers the next one I will discuss):
Its been mentioned a few times already but yeah, 686 is a rest at ease type of gun. I/we have a 4 inch 668 plus 7 shot 357 revolver and it gets a lot of love. It is a great shooter, plus its good for people who don't practice or shoot often, it won't "jam" on you from operator induced error. Nice and heavy, soaks up and dampens a good amount of recoil, and if push comes to shove it makes a good club being that its made out of stainless steel.
