Help needed on customizing sidearms
I've been given some older yet fun to fire sidearms that I can't find a lot of intel on they are; 1937 exercito brasileiro colt .45 and a model 107 millitary Supermatic tournament 22LR. Since my weapon of choice is my M24 with my Mk4 I'm not that well versed in customizing or pricing sidearms. What kind of customizations would help make these weapons a little more tactically reliable and what would one of these little beauties go for on an open market.
Thanks for the time
