I have a 657 that may be just a tad slow on the lockup. It sometimes backs up when fired, resulting in the hammer dropping on a previously fired cartridge.
If I cock it really slow, the bolt looks like it engages the notch in the cylinder, yet if I wiggle the cylinder, the bolt will engage farther for a more secure lockup.
Is this as simple as replacing a part? or should I send it in to Smith for adjustment. I can probably replace a part, but if it requires gauges of such, I don't wanna mess with it.
Any help would be appreciated.
