I purchased a new Beretta Neos last month and found that the trigger pull is as bad as has been discussed in this and other threads. It was a little stiff and heavy. The main issue I had was the long crunchy pull.
When I looked at the rear of the gun and watched the firing pin, I could see it move slightly to the rear just before it would release.
The "trigger job" post was interesting, but more work than I wanted to do. The gunsmith route seemed pretty expensive.
I fired 100 rounds of target ammo through the gun and dry fired it a couple hundred times and the trigger did not get any better.
Most of the trigger jobs I saw involved removing the sear and grinding down the firing pin shelf where the sear mates. Also, if you take off too much, it is hard to reverse.
I had some plastic 0.030” shim stock in my shop and thought it may be possible to build up the notch in the firing pin instead of grinding it down. It seemed like an easy way to reduce the length of the trigger pull.
It was amazing how much difference it made when I added a shim to the notch in the firing pin. Right now it is held in place with CA glue, if it does come loose, I think the spring and sear will prevent it from going anywhere. I built up the notch with this one shim, to what gave me what I think is a safe depth to engage the sear.
Now, the trigger pull movement is almost zero, there is no visible firing pin rearward movement. It is still a little heavy, but it feels right in all other areas.
There is a downside; the safety cannot be used. For me that is not a show-stopper because I never use it. My gun is never loaded or cocked unless I’m on the shooting range. I never consider a gun "safe."
I did fire 100 rounds to see if the fix would hold up and not double fire or go full auto on me. It worked great.
"Warning Will Robinson" When you mess with the trigger or sear on a gun, do so very carefully and expect that it may fire more than you expected, which is not safe. Or it may not fire at all, which is sort of safe, but a real bummer.
If you want to try this “fix” do so at your own risk. You may want to build up the shelf in 0.010” increments of brass shim stock till you get the effect you want.
