tanfoglio1911 Posted June 25, 2015 Share Posted June 25, 2015 I need help in which part I need to polish to smoothen the trigger pull of my STI Edge. The trigger pull right now is somewhere in 3.5 lbs but looking if I can lower it down to 2.5. Thank you. Link to comment Share on other sites More sharing options...
bountyhunter Posted June 25, 2015 Share Posted June 25, 2015 Going down to 2.5 really needs a gunsmith's attention IMHO. Link to comment Share on other sites More sharing options...

stardust tommy Posted June 25, 2015 Share Posted June 25, 2015 drop in triggerkit... means dropped in a bag and ready to sell... there are so much variables that you can't produce a safe drop in kit for a 2.5lbs trigger... with the stock STI parts you get far, secundairy cut on the sear, searspring adjustment, lower the hammerhooks...

Bigsampson Posted June 25, 2015 Share Posted June 25, 2015 Funny, I have tried 2 and know others that have used them w great success. Went from a measured 3.5 to 2.5. Safely Link to comment Share on other sites More sharing options...
dansedgli Posted June 26, 2015 Share Posted June 26, 2015 (edited) Take some tension off the left sear spring leg. Buy a spare sear spring if you are worried and do it to that. Takes 2 minutes and will do the job if my new lawman is anything to go by. Edited June 26, 2015 by dansedgli Link to comment Share on other sites More sharing options...

Do I need to bend it bankwards or away from the sear? seriously, have a gunsmith perform a trigger job. leafspring tension is to fine tune the trigger job and you can easily go on full auto mode if you are not careful.

He speaks the truth. Screwing with the sear spring force without knowing how to set up a trigger can cause the gun to multiple fire. As for drop in trigger kits: if the pins in the frame are tight to tolerance, they can work well. If not, you need a gunsmith to cut the sear angles correctly.

jcc7x7 Posted June 26, 2015 Share Posted June 26, 2015 Even with the so called "drop in kits" you have to(or should) adjust the 3 finger spring Not a difficult job but should be done with care and preferably some knowledge of what you're doing. As stated before, safety test it at the bench and load mags one round each to make sure no hammer follow then go to 2 rounds each for 8 or 10 mags. Its good for overall confidence in the work that has been done Link to comment Share on other sites More sharing options...
PatJones Posted June 26, 2015 Share Posted June 26, 2015 One round in a mag tells you nothing about your sear geometry, the slide will lock open. You need to have a live one in the chamber and a dummy in the magazine. I do this several times before I load more in the mag. Link to comment Share on other sites More sharing options...

Tochnost Posted June 26, 2015 Share Posted June 26, 2015 Have a trigger pull gauge at the ready so you can adjust the center and left springs properly through the stages of the trigger take up. And absolutely as mentioned above be careful with going too light. After you re-assemble you can "drop" the slide a few times with the trigger depressed to check for hammer follow, but when you go the range run one round in the mags a few times just to check and make sure your gun doesn't double or go auto. Besides the safety factor its a good way to get dq'd. Link to comment Share on other sites More sharing options...
