If you are on a limited budget or just don't shoot much, that is a very good way to do things But if you just love to shoot and shoot often, you can do more as your skill set increases. I grew up with Colt 'O' and Smith 'K' frames. They are quite different but I shot them alot over the years. Add alot of time on Browning High Powers in IDPA and SIG DA/SA series and well unless it's an oddball gun with weird safety/slide manipulations then I don't mind using 1911s, Glocks, SIGS, S&W DA/SA, etc... as well as virtually most revolver brands. But that is the catch. You have to make shooting your avocation in order to get that skill set. Otherwise just a few guns that work the same way as well as holsters. Deaf Wanna kill these ads?
