SickSilverado Posted September 13, 2020 Share Posted September 13, 2020 Hello yall. I have a new Defiant Limited Master. I did some polishing and installed the Henning flat trigger kit. I took it to the range and had what seemed like 2 light strikes, but looking back i think the hammer was at half cock. Now at home I've racked the slide several time to find the hammer following. I put the stock trigger back but it still does it. I clearly did something wrong, the under side of the sear face was chewed and beaten to shite. I replaced the sear but no luck. Maybe I have too little pretravel or too little overtravel? Anything else I should look at? Link to comment Share on other sites More sharing options...
SouperMan Posted September 13, 2020 Share Posted September 13, 2020 How many rounds do you have? Check the Sear Spring; that can also lead to hammer follow if it’s not lifting the sear in time/properly. Link to comment Share on other sites More sharing options...
SickSilverado Posted September 14, 2020 Author Share Posted September 14, 2020 I've put maybe 200 rounds through it. Link to comment Share on other sites More sharing options...
NoSteel Posted September 14, 2020 Share Posted September 14, 2020 Make sure your trigger is moving far enough forward to reseat fully. This was my issue when I was trying to get out as much pre-travel as possible. Link to comment Share on other sites More sharing options...
SickSilverado Posted September 14, 2020 Author Share Posted September 14, 2020 I took out all pretravel just now, still didn't work correctly. I disassembled and the sear is chewed up again. I resurfaced it, then tried again, and its chewed up again. What could be chewing the sear? Hammer is smooth as far as I can see. Link to comment Share on other sites More sharing options...
SickSilverado Posted September 14, 2020 Author Share Posted September 14, 2020 I found the problem, but not sure how to fix it. It was like you said, sear spring isn't moving the sear back to the default position. I swapped in i believe my 3rd sear(unica). I noticed all the sears get stuck when pushed i to the default position. Also, all sears are chewed up at the bottom after a few dry fires.

HesedTech Posted September 15, 2020 Share Posted September 15, 2020 (edited) Did you polish the sides of the sear where it contacts the cage? Polish the sear pivot pin, the sear cage sides which contact the sear and the sear sides. The only reason the sear would get stuck is a bad surface on one of the parts. Since you’ve tried multiple sears the cage inside surfaces could be your main problem. The sear should rotate smoothly in the cage even with a weak spring.

SickSilverado Posted September 16, 2020 Author Share Posted September 16, 2020 I did polish the factory sear on the sides like you mentioned. That one seemed to stick the most. Thanks for the link. I'll give his methods a try. Link to comment Share on other sites More sharing options...
