Differences in PSA LPK Triggers- markings and feel

**FromMyColdDeadHand** · 06-24-18, 01:24

Moment of weakness I got the Glock 17 and 3 lowers deal from PSA. Never know when Denver and CO will go full retard. Had some older PSA LPK MOE kits that I had bought a few years ago just to have around- and it seemed perfect for the three lowers. Since they were a Father's Day deal, I used them to teach my son how to assembly a lower. We got pretty good at triggers. Two LPK kits triggers weren't a problem and came in at 6-7 pounds, but pretty crisp. The third trigger acts almost like a two stage. About 6ish pounds with a few mm of travel and then a few ounces to fire. Seems almost like the disconnector is pushing the hammer more than anything else.

That trigger was in build two, and since it didn't seem right, we pulled the trigger from kit three- and it seemed fine. Put the trigger from kit two that was acting odd and put in lower three- same thing; lots of travel and a two stage feel.

We noticed the hammers looked a bit different, but the biggest thing was the good triggers had a letter (S?) stamped on the main body. You can't see it when the trigger is installed. The outlier trigger didn't have a stamped letter on it. I've installed, checked versus the other triggers and re-installed the trigger three- four times now.

The parts numbers are same on all three boxes of LPKs which were bought at the same time.

Does PSA have different LPKs?

Most of the LPKs I have don't have triggers in them, I usually go aftermarket- but with these lowers, I just wanted plain-jane standard builds. I know the mil-spec triggers will be variable and sub-optimal, but I didn't expect that big of a variance in feel and operation.

They have an EPT - polished fire control group in nickel.

Or WHEN you will get it!! Our mods should waive the requirement to contact the vender before posting complaints/issues. PSA complaints never would be heard!

And just like that, another PSA bash thread.

OP, with the voulme they put out, they almost certainly source triggers (and LPK's) from multiple vendors. If you are not happy with the trigger, contact them.

If you're a member on TOS, post this thread in their industry forum. Since there is nothing inherently wrong with the trigger, I'm not sure how they'll respond, but see what they say; they're usually pretty good about taking care of any issues.

It really wasn't meant as a PSA bash. It is a trigger operation question. For the life of me, I seem to remember some kind of discussion about triggers that operated like this- long take up and it seems like the disconnector is pushing the trigger off. The hammer really needs to be pushed down hard to reset the trigger with the trigger pulled to the rear. It's a MIL-SPEC trigger set-up. When proprietary stuff doesn't work, or something breaks or there is an obvious issue, I understand going to manufacturer.

Like I said, I don't run a lot of mil-spec triggers and if I didn't have two other ones to directly compare it to (and three lowers to test it in), I might have assumed that was how it was supposed to work. I also haven't ruled out something that I did. Spent at least 90 minutes just on this trigger versus another- swapping lowers. Haven't mixed parts because I didn't want to mix things up.

I really didn't think that it would be a PSA discussion, outside of the trigger markings being indicative of something. Like I said, I thought I had read about triggers acting like this, but with 20 years of the interwebs discussions in google, and all the links to upgrading triggers, I couldn't find it.

OP, you're good; my comments weren't directed at you.

Outside of 26 Inf, the other posters provided nothing of value to your question other than to bash PSA.

I hope someone more knowledgeable than I comes along and provides you with a substantive answer.

With that said, if you aren't happy with it, follow my suggestion and reach out to them on their industry forum on TOS. Josiah, the rep, is very helpful.
