Beretta PX4 Storm - Underrated is an Understatement!

I went ahead and ordered a LTT trigger bar, too. That and the hammer spring will have to be good enough.

Let us know how it goes!

I wish I had a trigger pull gauge. Let me see if I can do something about that, I’ve been meaning to get one.

I think Brownells has a good deal on those.

Nice work!

I have found that a little lube on a few contact points in the fire control unit can help, especially with new parts. I have found that it can reduce DA pull by a full pound sometimes. It can help perceived smoothness, also.

As to the Talon grips, you might peek here first: https://pistol-forum.com/showthread....n-usage/page10 post 91

This. Just as with Ruger revolvers, cleaning the assembly gunk away, making sure there are no burrs and/or leftover "wire edges" and then thoughtful lubricating can make a big difference with Beretta semiautos; sometimes this allows a somewhat heavier mainspring than originally projected.


My roll-your-own Talons were cut with as few narrow points, sharp notches or abrupt transitions as I could manage without being OCD, and - as you mentioned - they were made so that the gun could be disassembled and maintained without having to peel anything off. These are quite "minimalist," but they work for me. The two areas that wrap around the rear of the grip do overlap the centerline a bit. The Beretta "medallions" on the sides were covered up just because ornery old orange cats are no respecters of such things.

That's the thing about new toys, they require new support gear!

Annnyyy hints on what's coming in January? Not a PX4 and the 92 has already been seeing a lot of love lately with the 92X RDO, A4, and Carry Optics...

I guess this counts as a hint? https://pistol-forum.com/showthread....s-past-weekend

So playing off this comment and the one from Gato: with the TJIAB, there shouldn’t be any “wire edges” and things should be appropriately greased/lubed, no? That’s what the added cost above just buying a Comp trigger pack if for, the hand-fitting and polishing LTT is supposed to do, correct?

After a few dry fire sessions it’s smoothing even further, just wanted to clarify on those points. Thanks!

I have never purchased or used a TJIAB so we'll have to ask the other members if it comes lubricated. But, yes... that polishing is an advantage to the trigger job over the competition trigger group, stock.

There is an interesting concept about honing and smoothing interacting parts. When you hone or smooth a part there is less indentation, minor cratering or anomalies caused by tooling or casting. So, when two surfaces have been well polished in the correct way that they remain square to each other and flush there becomes more surface area that is touching more surface area. Meanwhile, there is less indentation or cratering to store lubrication in.

While the honing is reducing friction by making the surface more slick it is increasing friction by having more surface touching more surface. This is why some light lubrication is helpful for the parts to fit to each other as well as being individually honed.

This is another reason that I prefer grease to oil, as grease has a minor polishing effect.

I think this is where people were waiting for PX4 full size Carry to come back to Langdon - they sent out an email that they have them now.
