A very appreciable increase in performance. - TangoDown Vickers Tactical Carry Trigger

So first off, what people don't tell you is that if your replacing the stock trigger shoe on a Glock you have to beat the breaks off the stock trigger till you either A:break it or B:violently punch the pin out the other side of the shoe. So if you were to get this, I'd recommend ordering an OEM trigger bar with this unless you have a set of punches and a lot of pent up anger. But once you get the OEM shoe off it's as simple as putting this on the trigger bar and gently tapping the pin into place. Probably why they say "get a Glock certified armorer to install it" But Bubba can't read and could probably do it better anyways.

Performance: At first, function testing it and dry firing it at home barely felt any different than a stock trigger other than my finger actually feeling comfortable when I press on it as opposed the the abhorrently bad OEM shoe. Was kinda disappointed at first but then after taking it too the range and breaking it in with 200 rounds it felt SOOOOO much better. It is as advertised, you get more leverage and the perceived pull weight feels so much better. There's almost no much when you depress the trigger and it's just "smooth" all the way, and the reset feels nice and tactile. As far as I can tell as well, the pins didn't walk out and ran 99% reliable other than me limpwristing and causing a minor failure to feed. "Not the gun or trigger this was 100% user error!"

TLDR:A very good way to improve the feel on your 43x with out compromising the functionality of your internal parts unlike actual trigger kits. Best 40 dollars you can spend if you don't mind putting in some time and a little bit of elbow grease.
