Trigger and spring kit, takes up all slop and take up of stock trigger. Installation video moves a little fast, but installation isn’t difficult. Kit includes all tools necessary, aside from punches and lock tite. Adjustment took about ten minutes to find what I thought was a fair balance of reliable reset and no take up.

Looked at all the triggers on the internet over and over trying to make a good choice. After all I think we all are proud of our new toys and want the best bang for the buck, right!
Well I went with the MCARBO and this thing is Boss! Trigger pull average went from around 6lb to 3.5 and that’s the only change I made.
This was really easy install and adjusting it was no problem. I think I made a excellent choice for sure!

armyrat

What a difference

2/27/2023

Put this in my stock 320 full size along with the spring kit. Watching the video made install a breeze. Trigger pull went from around 6 lbs to an amazing 3.3 lbs. Take-up is all but eliminated. Love the feel of this upgrade!

Did not work as stated for Xten

2/23/2023

This did not work in my P320 Xten as it said it would. After install, made adjustments with said screws. It does not line up in the Xten as it was shown in a standard P320. The factory trigger was far better. I wouldn't trust this at all. Now it has glue on it so I doubt I can return it. However I plan on getting a 9mm P320 down the line, so I guess I'll hang on to it.

WOW!!

1/27/2023

Just got this trigger today, shipping was fast and could not wait to get it installed. I’m like a kid with a new toy, already watched the videos and was ready to get this thing together.
This was a really easy upgrade and what a difference in trigger pull weight. With my Lyman gauge the stock weight was 4.8lb average, after new flat trigger average weight was 3.7lb.
This was the only upgrade, no springs or anything else was done.
The adjustability of this is simply awesome, I am more than pleased with this trigger. It and the extended slide release is probably all I’ll do to it, but who knows?
Thank You my MCARBO Brothers!!

Great trigger

I thought the Apex flat trigger and trigger bar upgrade was good but the addition of your trigger with the TB is far better and with the WILSONCOMBAT grip module couldn’t ask for more
Well maybe unlimited ammo
Love the feel Of my 320
Thanks you guys for all you do and your service

Wow

I paired this with my Apex trigger bar and my x5 Legion. I shoot competitively in Carry Optics and can honestly say I have been thrilled since installing this trigger. It, along with the afromentioned accessory from Apex, has decreased my trigger pull to an average of 3.3lbs and an incredible trigger pull. My splits have decreased drastically, but it has a small learning curve as any modification does. Great job!!!! I'll be doing a review of it on YouTube soon.
