davsco Posted August 22, 2021 Share Posted August 22, 2021 so 2nd stage today, my hammer (sti 2011 with double sided safety) stopped locking back after shooting first target. so not sure what is causing that. trying to take the gun apart, but even with the hammer held back manually, i can't get the safety high enough to pull it out, normally halfway between off and engaged it isn't too hard to pull out. thoughts & ideas greatly appreciated!

davsco Posted August 22, 2021 Author Share Posted August 22, 2021 (edited) ok so working from bottom (msh) up i got everything disassembled... when i put it all back together without the slide, with manual cocking, the hammer started locking back periodically but then 100%. but with slide attached, if i rack it slowly it locks back most of the time, but almost none of the time when i rack it somewhat quickly. i don't see any damage or missing to the sear or hammer but maybe the pics and/or narrative will help someone please diagnose.

zzt Posted August 22, 2021 Share Posted August 22, 2021 First check the pre travel and over travel. You may have buggered up the sear nose and/or hammer hooks. Link to comment Share on other sites More sharing options...
davsco Posted August 23, 2021 Author Share Posted August 23, 2021 i will check. this is a dvc open in 38 super. i've had it since they came out and shoot it in a handful of matches each year so it hasn't been shot a whole lot. trigger etc is all bone-stock with no adjustments, unless something came loose etc. i have a couple of the brazos trigger kits (hammer, sear etc) in some of my other sti's and may try one of those in this gun to see what that does.

CHA-LEE Posted August 23, 2021 Share Posted August 23, 2021 Make sure the grip screws are tight and it’s not shifting on the frame. If the grip is loose it will cause all kinds of strange trigger issues. Link to comment Share on other sites More sharing options...
jim vaughan Posted August 23, 2021 Share Posted August 23, 2021 Check your leaf spring. It may have slipped off the sear sideways or it may be too short. Link to comment Share on other sites More sharing options...

On the 2011 Platform making sure that the grip screws are tight should be a frequent check. Any time you clean the gun double check the grip screws.

After you have written it at least 1000 times you should ask the moderator to put it every day in the 2011 thread automatically before any question in any questions about 2011.

Aircooled6racer Posted August 27, 2021 Share Posted August 27, 2021 Hello, make sure you have the overtravel screw so that you have free play after the hammer drops. If not back out the screw 1 full turn and try it again. Also check that you have the sear spring in the correct position and it has not slid off the sear.

davsco Posted September 1, 2021 Author Share Posted September 1, 2021 not the greatest pic, but would you say the sear spring is centered correctly and up high enough? where the bottom of the leaf spring plugs into the frame, there is maybe a playing card width of play up and down (with the leaf spring in that slot).

davsco Posted September 1, 2021 Author Share Posted September 1, 2021 so where the leaf spring bottom fits into the slot in the grip, i wrapped one layer of tape around the bottom of that slot, that at least in theory should keep the leaf spring stable and as high as possible. a layer of tape isn't much, and who knows how long that will stay in place, but after re-assembling, i did another 100 racks and the hammer stayed locked back until i pulled the trigger. is this just temporary luck again?

MikeBurgess Posted September 1, 2021 Share Posted September 1, 2021 in your picture the sear leg (left hand)looks like its under the sear, should be on top of the sear. Link to comment Share on other sites More sharing options...

davsco Posted September 1, 2021 Author Share Posted September 1, 2021 now that it's "working" I'll have to take it apart and check that sear leg. when installed and closed up, is there a way for the sear leg to get under the sear? Link to comment Share on other sites More sharing options...

NOSHMJ Posted September 3, 2021 Share Posted September 3, 2021 It sounds like you have hammer follow issues. It may be time to get a new sear spring or adjust the one you have. I believe its the left leaf. https://youtu.be/J_UAQ4SzQUI Link to comment Share on other sites More sharing options...

davsco Posted October 27, 2021 Author Share Posted October 27, 2021 so after getting it back working a 3rd time above, i just decided to send it back to sti and they sent me a prepaid shipping label. they looked at it today and i guess played with the leaf spring a little. says it's working fine (it was working when i sent it to them) and they're sending it back to me. i really hoped there would be an obvious fix (they said the hammer/sear engagement was fine) but i guess not. hoping the little tweaking they did fixes this issue.
