glknineteen Posted September 29, 2012 Share Posted September 29, 2012 (edited) So, I'm having occasional hammer follow with my slingshot reloads. It doesn't happen during livefire, and it hasn't happened so far if I put in a mag and drop with the slide release. Like I said, only happens occasionally, but that still means something is wrong, am I right? What parts might be the problem? Am I just going to have to replace the whole fire control group?

ipscjoe Posted October 4, 2012 Share Posted October 4, 2012 Sear spring tension. And check for any unsprung movement. Link to comment Share on other sites More sharing options...

glknineteen Posted October 4, 2012 Author Share Posted October 4, 2012 Ok, so after-maintenance update. I finally got a chance to do a complete tear down. Nothing seems wrong. My hammer hooks are in good shape, the sear and disconnect are like new, and although I put a little extra tension on the sear leg of my spring, the hammer follow persists. n If it helps anyone diagnose this, it's only on relatively aggressive reloads, and the hammer always slips to the halfcock notch. That means that either the sear leg needs more tension, or there's damage that I'm not seeing to the hammer hook or sear, right? Or am I missing something?

JaeOne3345 Posted October 4, 2012 Share Posted October 4, 2012 In my experience, the middle leaf of the sear spring has been the culprit for following. Link to comment Share on other sites More sharing options...
ipscjoe Posted October 4, 2012 Share Posted October 4, 2012 (edited) Lay the leaf spring in its slot and slide the mainspring in place (no beavertail). With a punch push on each of the leaves. If the spring moves and isn't in contact with anything then you have what's called unsprung movement. There is a fine line between a good light trigger and having the trouble you are having. Usually not enough tension is the culprit. Edited October 4, 2012 by ipscjoe Link to comment Share on other sites More sharing options...
glknineteen Posted October 5, 2012 Author Share Posted October 5, 2012 Thanks a ton guys. I'll try that out and report back with what I find. I'm hoping it's that simple! Link to comment Share on other sites More sharing options...
Powder Finger Posted October 5, 2012 Share Posted October 5, 2012 check that the top round in the mag is not hitting the middle leaf of the sear spring. (try all possible mag angles) at the same time make sure the spring does not touch the strut. (check from hammer down to full back) Link to comment Share on other sites More sharing options...
glknineteen Posted October 5, 2012 Author Share Posted October 5, 2012 Thanks again all...after teardown #2, I think the issue was insufficient tension on the sear from the sear leg. I think I get how this was creating the problem, almost like a "sear bounce" situation. Put more tension on the sear leg, and now I can't make the hammer follow. Problem hopefully solved.
