Single stage or 2 stage??
Matthew on May 29, 2019
BEST ANSWER: Bruh it says single stage in the description
How light does this trigger feel. I’m used to 4 1/2-6 LBS and a little nervous about the 3 1/2 pull?
Matthew K on Jun 1, 2019
BEST ANSWER: About a pound less than what you are use to.
Is this trigger flat or curved?
Benny P on Jun 20, 2019

How does it compare to a CMC trigger?
Derek M on May 29, 2019
BEST ANSWER: PSA makes very good parts. I have several cmc triggers and yes they are very close to each other. If you are looking for the best then buy Geissele triggers.

Will it work with the PA10?
MikeS on May 29, 2019
BEST ANSWER: Yes
Would this type of drop in trigger work in the new gen 2 KS47? Because that would be righteous! I have CMC’s in my other palmetto guns which work great.
Big Urn on Jul 2, 2019
BEST ANSWER: The KS-47 Lower will accept most aftermarket fire control groups (Geissele, etc.). However, due to the magazine catch geometry, one-piece drop in triggers such as CMC style triggers will not function in KS-47.
Will this work with the hybrid 9mm bolt in older palmetto 9mm uppers?
M. Martinez on Jun 9, 2019
BEST ANSWER: Yes
Is the spring on this hammer heavy enough to handle Russian steel case 7.62 ammo and primers?
Or will it result in lite strikes on the harder primers?
Building a lower for an AR47.
DaveP on Jul 21, 2019
Is this trigger full semi automatic?
Benny P on Aug 4, 2019
BEST ANSWER: Actually, "Fully" Semi-Automatic. For pleasurable Pew, Pew, Pewing......
Does PSA trigger address the slop movement associated with all drop-ins in the receiver? Tinmey uses tension screws or is it like CMC which has some slop movement inside the receiver
Steve on Jul 28, 2019
Can this trigger be disassembled for maintenance and parts repair ?
Anthony C on Sep 21, 2019
BEST ANSWER: I am sure it is possible to disassemble this trigger, but I do no recommend doing so.
I have two of these and they are a great value and in my opinion a very good trigger, crisp and clean break.
I plan on buying more for 4 builds I have in work for my grand kids.
For deep cleaning I remove the trigger assembly and drop it in my ultrasonic cleaner and run it through one or two cycles. Remove thoroughly rinse in hot water, blow it off with my compressor, then blow dry with hair dryer, re-lubricate and re-install.

Hope that helps - Tom
For the folks at PSA, will you start to install these as an option to your lower builds, like what you do with the EPT trigger now? Makes ordering from you easier and then there is no need to hold onto the EPT trigger after swapping out at home.
Derek P on Aug 20, 2019
BEST ANSWER: Hello,

We may be offering a few models with the trigger installed in the future. Right now it is a stand-alone product.

Best Regards,
PSA Customer Service
Will this work in a 5.56 AR? Or only 9mm?
amatuer hour on Oct 2, 2019
BEST ANSWER: Works in a standard mil-spec lower.
Will this trigger work with polymer lowers?
Stuart on Sep 7, 2019
BEST ANSWER: It should as long as the lower will accept mil-spec triggers in general. As far as I know, only the KS-47 lower would not take this or any other “contained” trigger due to its special spring for the mag release
what is the pin size ?
b k on Aug 13, 2019
BEST ANSWER: It comes with anti walk pins, mil-spec size. .154 is standard mil-spec so unless you have an odd ball lower or an older Colt then you should be good to go. 3 min install, and it's one of the best upgrades you can make.
Will this product work with. Diamondback ar10?
Curtis M on Oct 13, 2019
BEST ANSWER: The trigger fits into a mil spec AR15. AR10s are not mil spec. I have this trigger in a PSA Gen2 AR10 receiver. The PSA AR10 receivers follow DPMS specs, which uses mil spec AR15 triggers. If your Diamond follows DPMS specs then maybe or if Diamond says you can replace with any mil spec AR15 trigger then it should work.
Will this trigger work in PSA AR15 and KS47?
rokstar on Sep 12, 2019
BEST ANSWER: This trigger is pinned to the AR15 lowers only. It’s a jewel. Great break and the hammer hits hard. No complaints!
Will this work in my new PSA PA-10 gen 3?
James on Oct 15, 2019
BEST ANSWER: I used this trigger in my gen 2 (.308) build. It’s working great. No reason for it not to Fit in the gen 3.
Any chance of a curved trigger version coming out?
Steve H on Jun 28, 2019
BEST ANSWER: Well, I did not happen on 8-1-19, check back on 9-1-19...

Ken P on Jul 4, 2019

Great product!
This trigger is amazing and way cheaper than other drop in triggers. Everything is included. It’s installed in my PSA AR9 lower. Ran 250 rounds through it, not one malfunction or lite strike.

Go with a name brand
The pros: it looks great
Cons: Pin kit it came with had 4 screws, two keys, 1 I repeat 1 pin of that one pin only half of the pin was threaded. Had to use my extra JMT anti walk pin kit that is waiting for a different rifle just to install this trigger.
Reset feels weak.
When in safe mode blade gets movement then clicks, other drop in's I have do not do this, so it was a touch disconcerting, although may be normal operation for the PSA drop in.

In conclusion: It really isnt worth the 120 price tag (to me at least) my Blackops trigger from JMT is way better and under 100$.

PSA trigger group
Went out on a limb to purchase this trigger for one of my rifles I've had guys Lee triggers they're very nice triggers but let me tell you something the trigger pull has no take up . The wall is instantaneous approximately 3 lb the reset is amazing talk about extremely fast ability to shoot training is the key for this price I don't know how they do it extremely easy installation once you use this you will have a hard time not purchasing it more of them I have about six thousand rounds through the trigger group 0 problems so much for the guys Lee's if you have the money and you've ever wanted to try this type of a trigger group out don't hesitate the flat trigger is extremely nice well made straight out of the box crushing all of my friends on the range
