Tattoo Posted May 10, 2012 Share Posted May 10, 2012 (edited) Hey all, This just happened to my Limited gun the other day and its a first for me. Is this something that "can" happen under normal circumstances or do I have something wrong here?? T Edited May 10, 2012 by Tattoo Link to comment Share on other sites More sharing options...
cheers623 Posted May 10, 2012 Share Posted May 10, 2012 What gun are you using the sear spring in? If you are using a traditional 1911 sear spring in a plastic gripped 2011 type pistol they can occasionally wiggle too far to the left and the left most spring leg will slip off the sear. I believe Dawson makes a sear spring specifically for the 2011 grip or, you can do what I do and others do and take a small punch and dimple the lower outside edges of the sear spring at the bottom enough to raise the material out and take out the wiggle room in the grip. That way it stays put when you install it. Does that make sense you you? Am I describing what what the problem youre having is? Hope that helps, Cheers623 DVC Link to comment Share on other sites More sharing options...

It is a factory STI gun and I assume it came with a 2011 sear spring?? But it does seem to be able to wiggle side to much. I replaced the mainspring with a 17lb ISMI and put it back together. I thought maybe I did something wrong.....but it ran for over 300 rounds and then it happened?? Reaally lacking confidence in the pistol now. Thank god it was just a practice session. But I need to correct this. I thought maybe there was not enough tension on the sear spring from the mainspring housing?? And eventually the recoil caused it to shift to the left and come off the sear?? Thanks a lot for the advise! I really appreciate it T Link to comment Share on other sites More sharing options...
Ming the Merciless Posted May 10, 2012 Share Posted May 10, 2012 The SVI spring works well and is made wider for the 2011 style pistols. SVI Light Touch Sear Spring Link to comment Share on other sites More sharing options...
Tattoo Posted May 26, 2012 Author Share Posted May 26, 2012 Would having the grip safety ground off so that it does not touch the sear at all have any contribution to making the sear spring move and come off the sear?? T Link to comment Share on other sites More sharing options...
cheers623 Posted May 26, 2012 Share Posted May 26, 2012 It'll help a I tiny bit but not as much as preening the sides to remove the slop. Another suggestion is to wrap the bottom of the spring with masking or electrical tape enough that it won't wiggle and allow the spring to slip off. Try that. Hope it helps.

Aircooled6racer Posted May 27, 2012 Share Posted May 27, 2012 Hello: I have been using the Dawson sear spring for a while and they are great. The Ed Brown is also a good one. You can get them from forum sponsor Shooters Connection. That reminds me I should order some more Thanks, Eric Link to comment Share on other sites More sharing options...

T The grip safety never touches the sear. The grip safety contacts the back of the trigger stirrup when engaged, stopping the rearward movement of the trigger. The thumb safety is what blocks the sear. Link to comment Share on other sites More sharing options...
cheers623 Posted May 28, 2012 Share Posted May 28, 2012 It doesn't touch the sear itself. However it does touch the right-most sear-spring leg that provides positive engagement of the GS trigger bow stop arm. If you're going to disable the GS anyway, sometimes grinding/cutting off that stop arm will help keep the sear spring from moving in the frame channel as much. It's still a better idea to peen the sides of the spring to eliminate side to side play or just replace with a 2011 specific sear spring as mentioned above.

Cheers623 DVC I wanted to thank you all again for your help. I ended up going the route of least harm first and taped the sear spring. I shot a match with it and it ran great! The sear spring is a 2011 spring and does not move AT ALL now with the mainspring housing in place. I really learned a lot about the pistol taking it apart and I really appreciate all the advice! You guys rock! T Edited June 5, 2012 by Tattoo Link to comment Share on other sites More sharing options...
