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.

Rehydrating Dried Out Pipe Tobacco

I am an occasional pipe smoker, which means that sometimes my tobacco dries out before I use it. Hence this video from a friend:

I had a couple tins of tobacco that were several years old and rather crunchy. One tin was about half full, and after adding 6 to 10 drops of whiskey to it and letting it sit overnight, it was smokeable. It could have been a little moister, so I added a few more today.

The second tin was almost full and 6 to 10 drops wasn't enough to revive it, although I could tell the difference. I added another 10 drops today and will check on it tomorrow.

80% Glock Build

We've done 80% AR15s, so now it's time to build a Glock 19 from an 80% lower. Like with AR15s, this isn't about saving any money, it's more about flipping the bird to the man. You can pick up a perfectly serviceable used Glock for the same or less money.

I'm on a zillion lists already so blogging about this isn't going to make a difference for me.

Aside from that, it will be a great learning process so I know how Glocks work from the inside out. Glocks are among the most common handguns available so that's a good thing.

What's really neat about this is that because the receiver is plastic, it can be done entirely with hand tools. I've read of guys completing one of these in a half hour. That said, I plan to take my time and get it right.

Another nice thing from my perspective is that the Polymer 80 frames fix the uncomfortable-to-me Glock grip angle (the main reason I don't own a Glock).

The frames are compatible with OEM Gen 3 Glock parts, or aftermarket Gen 3 Glock parts. Gen 4 or 5 parts do not fit. Gen 1 or 2 may fit but Gen 3 is specified for these frames.

• Polymer 80, maker of the 80% lowers (also has polymer AR15 lowers).
• Nice article on Pew Pew Tactical detailing the build process with lots o' pictures.
• Massive thread on Arfcom with tips, notes about pitfalls, and pics of a bunch of builds.
• Another useful Arfcom thread.

The Polymer 80 kits and assorted parts are available from various online vendors including MidwayUSA and Brownells. However, I didn't want to have to source all the parts to complete the build separately, so I went to 80P Builder and ordered a "Ruiz Package" which includes the 80% frame, lower parts kit, and an assembled barrel/slide assembly. This package was a special and is now out of stock. (Fred Ruiz is a pro shooter/ex-SEAL sponsored by 80P Builder.)

Pic of the kit I ordered:

(Picture borrowed from 80P Builder.)

The kit does not include a magazine and 80P Builder only has ETS mags in stock, so I ordered 4 MagPul Glock 19 P-Mags from MidwayUSA. (I don't know how good the ETS mags are. They may be just fine.)

Note: The frame has a metal plate molded in so that if you want or need to add a serial number, you can do so. E.g., California builders can request a serial number from the CA DOJ for their gun to stay within the bounds of state law. This is not required on a Federal level. In my opinion, putting some kind of serial number on the gun is a good idea if for no other reason than identification if you need to file a police report for a stolen gun.

Polymer 80 also sells frame kits for Glock 17 and 26 size guns. While mine will be in 9mm, AFAIK you could build one in .40 S&W or .357 SIG as long as you get the correct parts. They also work with Advantage Arms .22LR conversion kits. Polymer 80 is supposed to be introducting G20 / G21 sized frames later this year, for those interested in a 10mm or .45 ACP build.

I got a shipping notice from 80P Builder this morning. They are located in Charlotte, NC, so I expect to have it by the end of the week.
