hav3n Posted August 13, 2017 Share Posted August 13, 2017 (edited) Hi all, I have installed: xtreme sear BOLO Titan Hammer Extended firing pin block PD firing pin reduced and regular power sear spring (tried both - originally reduced power was in) Initially after I installed the extended FPB I was able to push on my firing pin with the hammer back and it would catch correctly (manual safety off). Now when I push on my firing pin I'll get a little resistance (2lbs or so) and then the firing pin goes forward. Taking a look at the top of my sear where it engages the XFPB I see that it has a flat point on the right arm. Did i wear out the sear? Did i wear out the XFPB? Round count is probably 7000 or so on these parts. How do I fix this? Thanks. Edited August 13, 2017 by hav3n Link to comment Share on other sites More sharing options...
johnbu Posted August 13, 2017 Share Posted August 13, 2017 Id bet you DID NOT correctly fit the xfpb and the firing pin has been slamming into it. Look at the fpb and firing pin. New fpb and firing pin will fix it ... if that is the case. Link to comment Share on other sites More sharing options...

Look at the fpb and firing pin. New fpb and firing pin will fix it ... if that is the case. Ok help me out here...OK. So basically it seems that these tolerances are too tight to have a XFPB last too long. Basically my XFPB isn't moving enough to give enough tolerance and then eventually it gets worn. How do I adjust my BOLO to allow more XFPB / sear movement? Link to comment Share on other sites More sharing options...
SoCalShooter69 Posted August 29, 2017 Share Posted August 29, 2017 (edited) Pull your firing pin and block out. Take pictures. Upload them here. We will be able to determine your next course of action. There's nothing wrong with the sear. Don't touch the bolo.

If fitting is needed, it'll take place at the firing pin block. It'll be obvious if you show us the places where the block and the firing pin make contact, as johnbu and socal said.

Sc0 Posted August 29, 2017 Share Posted August 29, 2017 How did Tanfoglio get the DA pistols to work with the 1pc sear? Factory extended firing pin block? Link to comment Share on other sites More sharing options...

The one piece sear means the trigger bar is only pushing back one leg, instead of two. Link to comment Share on other sites More sharing options...
