I'll give ya a hunnert bucks for it.I think I recall reading that the hammer dog is a fitted part, therefore not available for purchase? If it is the hammer dog, this is the first time I've been burned buying a previously owned firearm. It sure is pretty though.
I had some trouble with the cylinder latch on my GP100, when I first began reloading .357 mags. Just enough unburned powder was getting under the star and binding up the cylinder. Sometimes the cylinder latch would not activate.Problem solved. Don't know exactly what fixed it. Seemed the cylinder latch button might have been the culprit? Squirted a lot of Ballistol into the frame, screwed the cylinder latch button screw tight, and then pulled the cylinder latch button out as far as it would go, a few times.
