- "Milling" the frame is easy. I used end nippers to remove most of the excess rail material, then filed and sanded them smooth.
- Assembly gave me some issues but mainly because this is my first "Glock." In particular, I had issues getting the slide stop in correctly so that it would either turn the gun into a single shot, or fail to raise at all. But I got it squared away.
- The "$0.25 Glock trigger job" is worth it. Before I polished several parts in the mechanism, the trigger pull was really heavy and gritty. Now it's a lot better and should smooth up with use.
- The Polymer 80 grip is an improvement for me over the stock Glock 19 grip.
I am left handed and found that the magazine catch rubbed on my middle finger uncomfortable, so I beveled the offending corner.
Not being a fan of the hole in the bottom of the grip behind the magazine well, I added a Strike Industries grip plug, which holds a combo flat head screw driver/punch, and a small oil vial. It had to be sanded a bit to allow magazines to drop free. Speaking of which, I bought four MagPul P-Mags from MidwayUSA to go with the gun.
I'm hoping to shoot it tonight on an indoor range. Range report to follow.
