Polymer 80 Range Report

I shot the Polymer 80 "Glock 19" last night. My dad and I put about 150 rounds through it, mostly Herter's 115 grain ball (made by Sellier & Bellot), along with around 25 rounds of my handloads. They were 115 grain Berry's plated bullets on top of 4.5 grains of Universal Clays in mixed brass.

The gun had one malfunction, a failure to fully go into battery with one of the handloads. Previously, I had some issues with this batch in my CZ P-09. AFAIC it was an ammo issue, not a gun issue.

Accuracy was OK, nothing to crow about. Most of the rounds went into a palm-sized group at 7 yards. The limiting factor for me was the trigger. Even with my fluff and buff job it is still pretty bad -- heavy and creepy. I'll see what it feels like after 500 rounds but if there isn't a marked improvement I'll look into getting something like an Apex trigger.

The other mod I have tentatively planned is a set of Heinie Straight Eight night sights.

After I finished shooting I field stripped it and saw no signs of unusual wear.

So far I'm very pleased with the gun.

Polymer 80 Build Complete

I finished up the Polymer 80 "Glock 19" today. Impressions:

1. "Milling" the frame is easy. I used end nippers to remove most of the excess rail material, then filed and sanded them smooth.
2. 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.
3. 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.
4. 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.
