I experienced a problem with my pre lock K-Frame. The hammer nose snapped. I figured it would be okay to keep dry firing it on snap caps for a bit (but jeez maybe I was damaging the frame in retrospect) and after about 100 dry fire cycles, the gun started locking up, trigger wouldnt work. I assumed it was the snapped hammer nose that got lodged somewhere inside.
I got the replacement hammer/nose today and installed it, same problem. With the hammer forward, the trigger wouldnt cock the hammer, it would get jammed up. I took it apart and reassembled and it seems to be working now. So I am not asking because I have to fix it, it seems to be fixed. I am asking out of curiousity so I can learn better how revolvers work and what caused this and what solutions for the future.
Also, I am worried its not that I reassembled the new hammer wrong, because as I said this problem started happening as soon as I snapped the hammer nose, before I ever took the gun apart, before I removed the original hammer. So maybe I didnt really "fix" it permanently, maybe I am just on borrowed time.
I snapped several pics.
First picture is where the actual binding is occuring. Excuse me because I dont know all of the names of the parts yet but I plan to learn! The trigger piece is supposed to interface like a gear inside the hammer, but instead its binding up here, as I am initially trying to press the trigger on a forward hammer:
Second picture is if I cock the hammer simultaneously as I press the trigger. It all seems to work fine when I do this. Whatever binding is occuring is removed if I "help" the trigger by manually cocking the hammer as I go and you can see the trigger nub properly connects into the hammer gear nubs:
These last two pictures are just of the gun cocked and uncocked, because maybe you can see something is assembled incorrectly:
So like I said, I took everything apart, including the hand (which fell out and I struggled to get the spring back in place lol), and reassembled carefully, and it seems to be working fine albeit a bit gritty on the trigger now, but I dont remember how it was before. I did install a whole new hammer so I wonder if the interface between the trigger and the hammer has to "Wear in" to smooth out over time.
I am asking as a learning experience, not a "help me save money I cant afford a gunsmith" question. I genuinely want to learn more about revolvers, this was my first time seriously taking one apart and it was a very fun 2 hour experience! I am blessed that I have two, and my second one is working fine so I took that side plate off and was able to compare and contrast.
