Hello Everyone! First off I would like to say that I am new to the forums and I was directed to post this question here!
So here it is: I have a S&W M&P 45acp that I installed an Apex Flat-Faced Forward Set Sear & Trigger Kit into and I have had issues with double firing. The gun is brand new and nothing else has been done to it and I had no problems up until this point. I think it might be the sear spring but not sure (it was recommended that it might be the sear spring this morning, I have not tried it yet). Anyway, when I initially installed the kit I put the weaker spring in and I really thought the trigger pull was a bit light, but nice none the less. Anyway, I had several "doubles" and I thought that it might have been the combination of the light trigger, the recoil and the fact that I might have been "riding the trigger" a little bit. So I install the heavier trigger return spring (the green spring) and test fired the gun and it did great, as a matter of a fact I ran it 2 complete matches with no issues..then this past Sunday at a match doubled on me 4 times in the first stage. Several fixes have been suggested the one that I am planning to try next is to replace the kit provided sear spring with the factory sear spring and if that does not work then I am planning to reinstall all of the factory parts.
Any suggestions are greatly appreciated and I would like to thank you all in advance. Also, it is very possible that I have something installed incorrectly this is my first trigger job so again any suggestions, comments, recommendations, etc...are greatly appreciated and thank you all again in advance.
