I watched a video where the guy shows how he fills in the small slot that's machined into the hammer of Colt revolvers. He claims this is what causes caps to be pulled off the nipple when fired and dropping it between the hammer and frame which he states and I agree, is common problem. He uses JB Weld to do this. Anyone here try this? Is it worth the effort? I'd try it and probably will anyhow, but I haven't got any JB Weld on hand at the moment. THanks.
