No kits as you can't have a free spin pawl on the Colt three screw lock work. Can't have a free spin pawl on the old three screw Rugers either. Serves no purpose on a Colt since when the gun is put on half-cock the chambers line up with the loading gate and the empties are easy to eject. The reason they came up with the free spin is because the two screw (actually pins) Rugers have no half cock and it is sometimes difficult to line up the chambers to eject the brass.
Well that explains it! I didn't know the rugers were that differant. I have to admit I was hoping there was some way to do it to my Uberti. I think that is so neat. I didn't want that mod done for anything else other than the coolness of it!
Can the mod be done to the two screw frame 1875 Remington repros? I do have one of those on my wish list.
