A few weeks ago, I installed a Wilson combat 12# hammer spring in my 92A1 and while I was waiting for the trigger bar to show up, I decided to run it and see if I got any light strikes. 350 rounds later, I have yet to get a light strike. The only other part that has been changed that would effect reliability is the elite 2 hammer and some light polishing on the hammer, trigger bar, and sear. I have tried it with Federal American Eagle, Speer Lawman, and Blazer Brass. Everything runs perfect in DA and SA.
DA pull is 7 pounds 1 ounce
SA pull is 4 pounds flat.
I ordered a couple of boxes of Tula and Wolf to see how far this can go. If anything will fail it will be the steel case. I will report back later in the week with results.
In no way am I recommending this mainspring for a defensive gun but I am amazed how much better the beretta trigger can be.
