Beretta 92 trigger pull weight

[MosinVirus]

Hello all,

I was just trying to see about reducing the trigger pull weight on my Beretta 92, and found that I was getting consistent double action fire with a 12# hammer spring. Not a single hiccup.

Ammo used:

Federal American Eagle 115 gr. FMJ
Freedom Munitions NEW 115 gr. FMJ
CCI Blazer Brass 115gr. FMJ

After spending some time with the springs (hammer and sear) and engagement surfaces, my trigger pull weights are:

SA trigger weight is 3.25#
DA weight is ~7.1#

My questions are:

1. Have you 92/M9 guys experienced any issues with running that low of hammer springs?
2. Have you achieved the same weights while still using higher power hammer springs?

I am using a stock trigger bar, steel trigger (not short reach), slightly modified sear spring, stock hammer and hammer strut.

Thank you.

This is not an answer to your question but I have read several posts stating it's common to buy the 16# D spring and then clip 2 or 3 coils off one end. Don't know what the resulting poundage is but could be close to yours.

Thank you. I can actually try this and see what I get. I have a couple of 16# springs around.

I look forward to your report!!

Yup. I have done both. Dave Olhasso and BUSA have the D Springs as does Brownells (in Iowa). The cut spring seemed a bit bush league, so I would support you buying a D spring. Do not order a Competition spring. They misfire (ftf) with the hard Federal primers.

I just tested mine with federal American eagle. It was fine. Which ammo has hard primers so I can check it out?

Federal.

Federal.

Sorry if I appear to be dumb... but, can you specify which Federal? They all have some sort of brandname - Champion, American Eagle, etc... I have been trying to search for Federal 9mm Hard primer, and am getting mixed results. I just want to make sure I try specifically the stuff that shouldn't ignite when using a light hammer spring.

Single action pull with stock hammer spring: 4.5#
Single action pull with "D" hammer spring: 4.0#

YMMV.

Not able to measure exact double action pull but it's a noticeable difference.

Got home and measured my trigger pull weights again with the 12# hammer spring in there. Consistent results to what I posted before (with DA actually coming out a little lighter at nearly 7#)

Here is what I experimented with (I am posting what I got)

	16#	16#cut		14#		14#cut
SA	4 lb	3 lb 9oz	4 lb 2oz	3 lb 11oz
DA	10 lb	7 lb 11oz	8 lb 9oz	6 lb 10oz

I own numerous Beretta Platforms and for the 92's, I found that the best approach is to use the OEM "D" spring in combination with the standard guiderod spring.

It will result in a smooth DA pull in the 8 pound range and a crisp SA pull in the 6-7 pound range, all with no frame battering and no light strikes.

I am not disputing that a 16# (or D) spring is obviously more powerful than a 12# spring. When I set out to see what I can do (learn) about Beretta 92 that I have I wanted to see what could be done about the trigger pull and comfort.

I started looking at the Wilson Combat line of parts and found an extended mag release, which was something I really needed, a bunch of springs, a short reach trigger that I thought I would like, but hated it, and a redesigned trigger bar that supposedly helps with light primer strikes when using low power springs.

Since I was out to learn, I wanted to see how light of a spring would impede functionality. So I got the new trigger bar, fitted it, installed the lightest power spring and went to the range.

I may still make a video of this whole endeavor, so the plan was to go to the range and take tools and various parts with me to troubleshoot right there on the spot.

I decided to return the original trigger bar into the gun and take some footage of the gun failing with a 12# hammer spring in DA. And... It didn't.

On video I shot 15 rounds of each of 3 different 9mm brands I had (total of 45 rounds), and there was no light primer strikes. At all.

Let me know if you guys want to see the video. By the way, decocking the gun before every shot is no fun.

Wally Mart Reddish label. One of the cheapest ammo boxes they sell.
