Some older Remington's, Shotgun Model 11 from 1925 and a pair of Model 51 Pocket pistols from 1923.The Model 11 had to be reworked, the firing spring had disintegrated, I still need to fine tune the stock fit but it is mechanically strong now. The pocket pistol was a back up gun for a few years in the early 70's.
Not sure if you guys consider this oddball on a 1911 site, but this is one of 2 38 special wadcutter factory colt N.M. that i have. From the outside they look like any 1911, inside things are very different.
Not a firearm but an interesting weapon. It's made for Olympic rapid fire. 5 shot magazine. Front sight is exchangeable, rear sight notch width is adjustable, trigger blade is adjustable for length of pull and blade angle, grip angle is also adjustable.
