12 lbs Hammer Spring
I bought the new Beretta 92x Performance and while it has a good trigger it wasn't as light as others have reported. So after watching Ernests' YouTube video on hammer springs I ordered a couple of his Chrome Silicon springs, an 11 and 12 lbs. I installed the 12 lbs spring in my 92x Performance and it dropped the DA weight by about a pound and the DA pull by 3/4 lbs making the trigger now what I'd call great. I like the trigger so much now with the 12 lbs spring I didn't even think about trying the lighter 11 lbs spring. Plus the 12 lbs spring was 100% reliable with all the ammo I tried in my pistol.
