I have a 25-13 MG 45 Colt that was OEM with the lock.
The action/cylinder rotation seized several times on me, and this was with mild loads.
I removed the lock and it's been fine since.
I didn't take careful note of the circumstances of the seizure; I just knew I was removing the lock a.s.a.p. after I got home.
b/t/w...I couldn't care less re the cosmetic hole issue.
