Endall Posted January 22, 2022 Share Posted January 22, 2022 Decided to install one of these on a full size large frame Witness. The trigger fit tight on the trigger bar. Seems to work fine. But there is no pocket to install the short leg of the trigger return spring. Fought it for a couple hours and reinstalled the Tanfoglio double action trigger. After practicing with Extreme trigger, it took maybe 15 seconds to push the spring and pin it in place. I wanted to install a second one in one of my other Tanfoglio guns. Is there a trick to finding a hole to stick the short leg into? At least on the standard Witness trigger bar there is no gap for spring with an EG Extreme SA trigger.. Think the trigger bars are all the same. Link to comment Share on other sites More sharing options...
himurax13 Posted January 22, 2022 Share Posted January 22, 2022 I usually take a bastard file and trim off the front right corner where the trigger bar hole is for the trigger to create that pocket. I do this for CZ75's as well. Link to comment Share on other sites More sharing options...
Endall Posted January 22, 2022 Author Share Posted January 22, 2022 I did not know think about hogging out a hole for the spring. May shoot it a little and tear it down again. There is a LOT of takeup now with disconnector pulled and a double action trigger. This Xtreme SA trigger is disappointing if you have to modify it to be able to use on the gun it is designed for. I fought for a couple hours trying to find how to stick the short end of spring inbetween the trigger and trigger bar. Guess that is why there is a Version II.

Endall Posted January 23, 2022 Author Share Posted January 23, 2022 Himurax13,, Cannot stand the shape of the trigger and the take up to fire. Been too cold to go to PSC and test out. Going to modify and install the Xtreme trigger back in. One dumb question, you are filing the corner of the trigger bar to create a hole for the trigger return spring? I wanted to modify the trigger, and not maybe weaken the trigger bar. Plus if I damage something I have three triggers and one trigger bar. Slotting the steel trigger will be a Dremel job.

Endall Posted January 28, 2022 Author Share Posted January 28, 2022 Eric Graufel sent a picture of the modified trigger for use with this vintage Xtreme Tanfoglio SA trigger. Did want to modify the trigger bar to work with his trigger, modified the trigger to work with my gun. Hogged out a channel inside the trigger with a flat metal file. There needs to be room right under the short leg of the trigger return spring to allow it to seat properly. The Xtreme trigger must have better leverage. Pull dropped from 3 LS,6 oz to 2 lb,7 oz after installation. No side to side movement also. There is a Version II Tanfoglio SA trigger. States drop in install. Must have a hole to capture the trigger return spring. Link to comment Share on other sites More sharing options...
Frankl03 Posted February 22, 2022 Share Posted February 22, 2022 I have this trigger installed in my Limited. The pre-travel is adjusted great with almost no take up. How do I adjust the over-travel? I know its the screw in the front of the trigger. Do I turn it clockwise to take out over-travel? Thanks! Link to comment Share on other sites More sharing options...
Endall Posted February 23, 2022 Author Share Posted February 23, 2022 Yes, turn clockwise so the screw protrudes further from the backside of the trigger. I like to adjust until gun does not fire anymore, then back it out to desired overtravel. Do this while dryfiring. Link to comment Share on other sites More sharing options...
