I have a quick question for you folks. I just got back from spending 9 hours out in the woods hunting. When I got back to the house I went to wiping down my firearms as always, and noticed that the retaining pin for the rear sight was protruding from the left side of the frame. No big deal really I just used the plastic handle on a screwdriver to put it back in place. I just don't understand how it worked loose though, all I was doing was walking around as usual, just glad it didn't decide to leave. So my question is is this pretty much par for the course for these sights? And what can I do to keep this from happening again if anything? The last thing I need is to need to rely on the revolver only to find the rear sight went AWOL.
