.45 Shield Performance Center Trigger Question

[Redcoat3340]

I recently acquired a .45 Shield, PC, M2, ported pistol. It's replacing my CS45 as my #1 .45 carry piece.

The trigger is just fine (if a tad light at 4lbs) but I have confidence in carrying it.

One question however: there is a noticeable "bump" or drag or grit or something in the takeup about halfway to the "wall." After that, wonderful; very crisp for a striker-fired gun.

I'm curious as to what that is. And is there some way I can eliminate it. It isn't a huge deal, more of an annoyance when I dry fire with a laser snap cap and I semi stage the trigger (pull back to the wall, then take the shot). If I just press though the trigger from scratch it just feels like some grit.

I'm semi-sure it has something to do with the drop safety, but can someone with a bit more understanding of striker-fired guns help. (All my pistols except for the .45 Shield and 3 SW99s and one Sig 320 are hammer-fired. Also,. I don't get the same "bump" with the Sig or 99s.)

Thanks.

Sorry, I can't answer your question, but I have a question. Why is it even a concern worthly of making changes to a fictional and a, so far, reliable self-defense?

You pull to the wall and break the shot. Then you have 6 more shots that you will not have to deal with the full take up. You stated that you believe it's causing issues when dry-fire with a laser sight. Well the take-up happens before the break. At the break point, what you've described should not affect your shot either way. If you get to the "wonderful" and "crisp" break with a 4lb trigger and are still having problems with keeping everything aligned when the shot breaks, then it's you IMHO and not the gun.

You are probably feeling when the trigger bar's ramp starts lifting the striker block. That can be smoothed out by some careful polishing of the ramp on the trigger bar and the striker block's dome and channel. Or install an Apex trigger/action kit. Or just pull the trigger a thousand or so times....

While it can be an annoyance, as Infidel137 indicated, over time and some shooting, that area on the trigger bar will smooth out and the issue will disappear. You can speed the process up by polishing that area of the trigger bar. Although many start polishing the drop safety plunger, I find it's already smooth enough to begin with. The trigger bar on the other hand is a stamped part and the edges where it was press-cut are seldom if ever smoothed at the factory. If you look at the edge that initially pushes against the plunger as you pull the trigger, you'll see it looks rather rough. While you don't want to remove any material from the top, you can take some fine sandpaper and smooth that leading edge a little then polish it and the top with some Flitz or mag polish. Once this is done, you'll notice the take-up is much smoother.

While I agree with Well Armed that if the gun is functional and reliable it's not a life altering concern, however we all have certain expectations, and if a smoother take-up meets yours then why not make it so. Good luck and good shooting.

PS...The PC ported Shield .45 is a great choice, it will serve you well.

I agree with the trigger bar dragging on the drop safety as the most likely cause of what you are feeling. However, a recently acquired pistol has a polymer trigger that fits so tight in the frame I wonder if it is touching.

Just for the record:
1. It isn't a big concern; it not really a "concern" at all. Mostly just it's curiosity, an opportunity to learn more about striker-fired pistols, and if the fix is easy (like some careful polishing), why not do it?
2. It doesn't affect my shooting a bit and I'm not blaming the gun for anything. It's just there, and not there on my, for example, Sig 320. So I simply wondered, "Why?"

In sum: The issue is minor, the opportunity to learn from people who know a lot more about this type of pistol is why this forum exists, and as they used to say in the Bronx, NY, "What could it hurt" to ask.
