How a Glock works
Creepy robot voice and strange looking finger aside, this is a pretty cool animation from Lone Wolf Distributors:

How my Glock 20 works…with a Lone Wolf barrel? Practically speaking? Not at all.

What ammo are you shooting, Lyle? Mine has worked well.

Hornady 180 XTP defense rounds, and also handloads of the same measurements with the same bullets in new Starline cases. Not exactly an obscure load. Either one jams on feeding due to the tighter chamber. Also an RCBS 200 grain cast bullet, designed for the 10 mm Auto and loaded to spec, specifically for which I bought the barrel – identical jam. I detailed it on blog.joehuffman.org (with photos) some time ago. LWD said they probably had a solution, but would never talk to me after making that initial assertion. I left several messages and nothing.
The case gets bitten at the front of the chamber and stops while it is angling up from the magazine. It’s locked in there tight, and leaves a gouge in the brass.
I have calipers. I know how to use them. My ammo is in spec (and more consistently so than the expensive factory defense rounds, I might add) and the factory stuff I tried does the same thing. Those rounds that do manage to get chambered result in a noticeably delayed “ker..chunk” action. Maybe there is some factory load with a shorter, more rounded bullet nose that will feed in it, but I have no use for picky eaters.
To me it looks like a simple trade-off; you have a looser chamber that feeds reliably, or a tighter one that’s more finicky. So I could polish and polish that portion of the chamber opening where the biting takes place, and probably make it work. It’s easy to see where the interference is happening. Bu then I’m not sure I’ll end up with a chamber that supports the case much better than the Glock chambers. The LWD feed ramp is obviously higher, with more support there underneath the chamber at the back, and so that’d be the other place to work down, making it thus more like the Glock ramps, which work very well but don’t support well under there…
I put the barrel away in its container over a year ago and haven’t looked at it since, other than to try it in my new 20 and find no difference in feeding. I wrote another barel maker about the trade-off concept (tight verses reliable), and they never responded. I guess they’re selling everything they can make, as fast as they can make it?

A lot of this probably comes from the big names in ammo loading the 10 so far below its original spec vs the boutique companies loading to the norma pressures. That whole “fully supported” debate.
Those Gen 2 factory barrels definitely left a lot of brass uncovered which causes that “Glock Belly” on the spent brass from full-house rounds.
I have shot mainly the hard cast stuff from Double Tap and Underwood, but I did shoot quite a few of the Double Tap defensive load with the 130 grain nosler, which is more rounded.
