A couple of thoughts. I have been shooting a Glock since 93 .
I use a stock minus connector , works well ,
I agree on the smooth trigger a lot of rounds and hot ammo and the grooved trigger beats your finger up.
Sights for those that like the stock sights the factory offers metal ones for $20 . This gets you a screw on front sight that will not fall off at the wrong time . BTDT. When I had stock sights I sharpie the rear black as well it was faster
The Vickers mag catch is about the same as a catch Glock offers overseas it is in between the two they offer here.
Funny.... I used to sharpie out the rear goalpost too because it was too "busy" & I wanted to be able to focus on the front sight w/o distraction.
