unclez Posted December 5, 2006 Share Posted December 5, 2006 The front pin on my rear STI sight keeps backing out after 200 or 300 rds. Luckily I saw it the first time before it fell all the way out and I pushed it back in. Well like I said, it's doing it every 200rds or so and I'm tired of having to keep check on it. Was thinking about staking it back in but wanted to hear some other options from you guys first. Zack Link to comment Share on other sites More sharing options...
Trader Posted December 5, 2006 Share Posted December 5, 2006 (edited) The last time that happened I used a decapping pin to replace it. The original pin is probably broken in two pieces. Edited December 5, 2006 by Trader Link to comment Share on other sites More sharing options...
unclez Posted December 5, 2006 Author Share Posted December 5, 2006 It's not broken. I can pull on the end that walks out and see the other end pulling towards it. I've seen the decapping pin trick but would like to keep the original as long as it's still in one piece. Zack Link to comment Share on other sites More sharing options...
SteveZ Posted December 5, 2006 Share Posted December 5, 2006 I had the same thing happen on my newly acquired STI Edge. I took a very thin drop of green penetrating Loc-tite and applied it to one side of the sight and then started working the sight hinge back and forth (removed the adjustment screw prior to doing this). The loc-tite did the trick. The pin doesn't drift at all now yet the sight is still free to move. Link to comment Share on other sites More sharing options...
yoshidaex Posted December 5, 2006 Share Posted December 5, 2006 (edited) try using a automatic center punch and flare one or both ends of the pin SLIGHTLY. If you flare the pin out too much, it may get stuck in there and you won't be able to get it out if you ever need to replace the pin. Don't stake the sight itself. Replacing a pin will be cheaper than a sight. Come to think of it, most of my repair suggestions involves center punches .........

SmittyFL Posted December 5, 2006 Share Posted December 5, 2006 Punch, allen key, drill bit, anything but the orginial pin will work. You may want to keep it, but it will just fail you in a match. Find something that fits snuggly, use a bit of lock tite and you're good almost forever. Link to comment Share on other sites More sharing options...

Haha Matt Seriously any suggestion will work but I would replace it. I have seen a drill bit more often used Link to comment Share on other sites More sharing options...

Hate to sound like a newb, but can anyone tell me what a "decapping pin" is, sounds like something I should have in my tool box, just in case!

Hate to sound like a newb, but can anyone tell me what a "decapping pin" is, sounds like something I should have in my tool box, just in case! Its on a reloader. The sizing die has a pin in the center that "decaps" or pushes the used primer out Link to comment Share on other sites More sharing options...
Gregory_k Posted December 13, 2006 Share Posted December 13, 2006 Decapping pins are the pins that punch out a spent primer in the sizing die for reloaders. Link to comment Share on other sites More sharing options...
CDRODA396 Posted December 15, 2006 Share Posted December 15, 2006 BSeevers and Gregory-k, Thanks for the reply, I still dont know what one is, but now I know why! I'll check with my reloading bud and have him show me one...thanks again. PH Link to comment Share on other sites More sharing options...
jwat Posted December 15, 2006 Share Posted December 15, 2006 I've had two break in the middle. One happened at a state match. Automatic center punched each end on top of the pin holes. Still using the same sight. Link to comment Share on other sites More sharing options...
Singlestack Wonder Posted December 15, 2006 Share Posted December 15, 2006 I beleive STI uses Champion Sights with their logo engraved. You could contact Champion for a replacement pin. Champion Sights Link to comment Share on other sites More sharing options...
