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?

Will this work in an AR 9?
Billy on May 29, 2019

How does it compare to a CMC trigger?
Derek M on May 29, 2019

Can you get the trigger shoe in different colors?

Will this work with the hybrid 9mm bolt in older palmetto 9mm uppers?
M. Martinez on Jun 9, 2019
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.
Does ANYONE read the descriptions that accompany the products? Apparently not.
David R on Jul 14, 2019
How many pounds is the trigger pull?
Benny P on Jul 6, 2019
BEST ANSWER: It's only in pounds when you buy it in the UK (University of Kentucky).
It's in dollars when in the US.
Does this trigger have set screws in the body to prevent wiggle?
Ken P on Jul 4, 2019
Any chance of a curved trigger version coming out?
Steve H on Jun 28, 2019
BEST ANSWER: Sure. There's a chance. Check back on the 1st.
Has anyone tried this trigger in the ks-47 ??..
Adam d on Jun 25, 2019
BEST ANSWER: It probably will not work without modification due to the Fire Control pocket not being large enough to accommodate cassette style triggers.
Will this work in a PA-10?
Steven S on Jun 18, 2019
How do I know if I have a gen 4 9mm BCG?
Noah S on May 30, 2019
BEST ANSWER: The bolt will be engraved with G4 on it.
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.

I would easily recommend this to anyone looking for a quality trigger at an affordable price
Fit and finish of this trigger seemed nice it was easy to instal with supplied anti walk pins yhe trigger has a nice crisp break the reset is a little different but it was easy to get used to only have about 60 rounds down range with it but I must say I'm impressed

Amazing trigger!
Installed on my 9mm Glock lower. Installation was a breeze. 10 minutes and you are good to go. Release on this trigger is very crisp and reset is great. I like this trigger more than my CMC I have. Would highly recommend!

Great Trigger for the money
Easy install, Nice crisp single stage trigger with just a tiny bit of takeup then a nice firm wall. All of these drop in triggers have a little "wiggle room" this one is no exception, but is much better than some of the CMC triggers that I have felt.
