Works well with stock triggers 09/03/2018
Using just the hammer spring brought my stock triggerâs pull down from 8lbs. to 5-5 1/2 lbs. with a consistent break. Using the JP trigger and disconnector springs brought the trigger pull down to about 4 1/2 lbs. but the break wasnât as âdistinctâ for me, so I went back to the stock trigger and disconnector springs. No FTFâs so far after shooting 200 rounds of various ammo ranging from match to duty to foreign surplus. This product exceeded my expectations.
Doesnât help with a stock trigger 24/02/2018
Found out the hard way these won,t change a thing with a stock mil spec trigger. These look to have the exact same hammer spring as mil spec. Bottom line I had the exact same 8 lb. trigger pull after installing these. Do yourself a favor and get the 3.5 version if you want a reduced trigger pull weight. Just make sure to test the reliability with all the ammo you use.
