I see no reason not to IF the pistol in good shape I would spend a few $ for a new recoil spring as the other is getting old. CorBon ammo is kept in SAMMI specs. I don't belive it will feed the reliabilty as was made during times of ball only. But never know. I got a USGI,1941 Colt that I shot for years Installed new barrell few years back because other worn out Rest of gun 1941 even use for CCW now and then.:blues:
