Gdub Posted February 23, 2015 Share Posted February 23, 2015 I installed a Delta Extreme hammer and a one piece sear in my stock II that already had most of the go fast parts installed. It dropped both SA and DA trigger pulls by 1# each. Is that normal or did I just get lucky? My SA trigger pull is now 2 lbs. 13 oz. and my DA trigger pull is now 6 lbs. 11 oz.

Gdub Posted March 18, 2015 Author Share Posted March 18, 2015 Which spring? Link to comment Share on other sites More sharing options...
adrianmdq Posted March 18, 2015 Share Posted March 18, 2015 I thought that you had changed the springs hammer too. Link to comment Share on other sites More sharing options...
RobertLx Posted March 18, 2015 Share Posted March 18, 2015 Did you also put in the interrupter that should be used with the one piece sear? The trigger shouldn't change much or even anything on the pull weight. I have the stock trigger and I'm getting 6#10oz DA and 2#8oz SA. This is with the Titan hammer, one piece sear, interrupter, and some light springs. Link to comment Share on other sites More sharing options...
Gdub Posted March 18, 2015 Author Share Posted March 18, 2015 I was told it had an EG light hammer spring in it already. Yes I installed the interruptor for the one piece sear. Although, Eric Graufell told me I didn't need it the factory interruptor should work with a one piece sear. Link to comment Share on other sites More sharing options...
ogiebb Posted March 18, 2015 Share Posted March 18, 2015 i have always used the stock interuptor as well when i switched from a 2 piece sear to a 1 piece sear Link to comment Share on other sites More sharing options...
bayougump Posted March 18, 2015 Share Posted March 18, 2015 I guess I was unaware of a special interruptor going with the one piece sear. I only have just used the factory one and given it a good polish on the friction points. My DA on my Stock II's are both around 5.75# if memory serves me correct and SA is in the 2.0-2.25# range. I don't have a fancy trigger pull gauge but that's close. I like the delta hammer but put the Xtreme on both mine and I noticed a little improvement in SA but the hammer seems to hit harder and reliability is more paramount to me then trigger weight. On a side note and not meaning to thread hijack but if anyone has a Limited in .40 or a Gold team in .38 super that's in great condition I have a Stock II in 9mm and a Stock III in .40 I'd entertain trades for.

RobertLx Posted March 18, 2015 Share Posted March 18, 2015 I wonder if there is any difference in using the stock interrupter vs. the one piece sear interrupter, as far as trigger weight. Link to comment Share on other sites More sharing options...
AlphaSeeker Posted March 24, 2015 Share Posted March 24, 2015 I doubt the interruptor would change trigger weight - I do hope it reduces some of the takeup. Just got my hammer, sear and interruptor yesterday, will compare to stock dimensions a install on wednesday. Will install in Stock 2. Lighter hammer spring has already made a big difference and polishing the trigger mechanism will be a big improvement. Stock components are very gritty. I did experiment with an oversized interruptor in my Stock 3 and made a huge difference - use it for Limited and Steel, since it is not production legal. You can check out my posts on the subject.

Adam B Posted March 24, 2015 Share Posted March 24, 2015 Question, how do you figure the Cgw disco isn't legal in Production? In ipsc it isn't but uspsa it is. Link to comment Share on other sites More sharing options...
AlphaSeeker Posted March 24, 2015 Share Posted March 24, 2015 The CGW disco is not used by Tanfoglio and is intended for the CZ. If Eric made it and it was blessed by Tanfoglio, it would be legal. Same with the Eric firing pin vs Henning - one is production legal, one is not. Link to comment Share on other sites More sharing options...
Adam B Posted March 24, 2015 Share Posted March 24, 2015 from how I read the rules you can use any firing pin and cgw disco and still be legal, internal mods are ok, otherwise every lightened glock striker and custom connector wouldn't be production legal either Link to comment Share on other sites More sharing options...
Adam B Posted March 24, 2015 Share Posted March 24, 2015 plus the cgw part isn't a factory part and many people, myself included, have them in their cz production guns and no one has ever said a word about it not being legal Link to comment Share on other sites More sharing options...
AlphaSeeker Posted March 24, 2015 Share Posted March 24, 2015 (edited) I believe CZ Custom shop uses CGW disco's and other parts - Tanfoglio does not [at least not openly]. Have not checked in the last year but, a year ago Henning's pin was not production legal - as per Henning. Eric's is legal. Eric is Tanfoglio at this time, Henning is not. The LDA parts site explicitly states that Eric's pin is "legal for production" - as of last week. I have Henning's pin in my Match also [sC gun]. I would love to use my CGW diso in production - spent much effort to fit it to my stock 3. The CGW one piece sear I use in my Match is tuned for almost zero pre-travel of the Henning trigger, but it is not legal either. CGW told me that these parts would be disallowed for use in a production Tanfoglio. Hope that you have better info and that the gods of USPSA give you a different answer than I got. I've never seen a disco inspection at a match so this may not have any practical impact. Edited March 24, 2015 by AlphaSeeker Link to comment Share on other sites More sharing options...

BeerBaron Posted March 25, 2015 Share Posted March 25, 2015 Alphaseeker. I think you have a confusion with ipsc vs uspsa production rules. In uspsa any brand internals are ok. In ipsc they have to be manufacturer options. The old henning pin was not production legal as you had to remove the firing pin block which is not legal in prod div. the current henning pin is uspsa production legal Link to comment Share on other sites More sharing options...
AlphaSeeker Posted March 25, 2015 Share Posted March 25, 2015 Happy to hear this. Opens up a lot more room for tinkering. Link to comment Share on other sites More sharing options...
AlphaSeeker Posted March 25, 2015 Share Posted March 25, 2015 Installed the Titan hammer, one piece sear and disco. Can not engage the safety now. Top leg does not allow clearance to engage the safety. Anyone else had this issue? I thought this was a drop in. Link to comment Share on other sites More sharing options...
Prov1x Posted March 25, 2015 Share Posted March 25, 2015 The hammer should be drop in, the sear I bet, is the problem. You will need to relieve the arm of the sear that is blocking the safety. As far as I have read, that seems to be the fix. Link to comment Share on other sites More sharing options...
BeerBaron Posted March 26, 2015 Share Posted March 26, 2015 you need to fit the sear to the safety. this is normal. nothing is ever 100% promised drop in. the bump on the sear that the safety engages needs to be fitted. or you can fit the safety to the sear. that way assuming all new sears are the same they won't need fitting in the future. personally since the sear is cheaper I'd do the fitting on that... cheaper to replace if you fudge it. tip: don't get impatient with all the removal and refitting. take it slow. little bit at a time then refit and test... rinse and repeat till it works.

AlphaSeeker Posted March 26, 2015 Share Posted March 26, 2015 I already fit the sear and all is functioning as advertised. Looks like the new sear is case hardened. Would think that a part that requires metal removal would be fully hardened to prevent wear after fitting. i am going to install the CGW disco, since the one recommended for this hammer does not reduce pre-travel.
