I recently traded into a nice 25-5 4" in 45 colt. I trigger felt rather good actually. However, the nosy side of me (call it suspicious if you will) had me removing the side plate for a "good cleaning".

While I don't have pictures yet (I reassembled it) I am on the lookout for a new hammer, & possibly a trigger. Someone appears to have used a dremel buffing wheel and rubbing compound on the trigger contact surfaces. Well past the hardened surface I'm certain.

I'm still happy with it for what I have in it, but it ain't over yet........

While I'm pretty comfortable tinkering with my Marlins, I don't feel confident enough to do more that parts swapping on a S&W.

I really enjoyed the photos & discussions above.
