Chamber length and lug differ from other brands slightly... didn't work for my custiom application - TRYBE Defense Glock 20 Match Grade Non-Threaded Pistol Barrel

I'm building one-off custom guns based on the Glock 30 and 29. One (30) is 45 ACP and the other (29) is 10mm. To do this, I'm combining a G30 slide (I have a Gen 3 and a Gen 4 slide) onto a custom G21 shortened frame. The G30 went together well with a LWD G21 barrel cut to length and custom length recoil spring, and it runs beautifully.

The 29 was a different story. The slide will not go onto the frame unless the slide lock is pulled down- this is a barrel issue. I can't get it to chamber a round out of the mag- the setup uses 10mm specific parts in the slide and also an OEM G20 mag. I pulled the barrels and looked at them closely. A picture would be worth 1K words, but I don't see a way to attach one. The enlarged portion for the chamber is slightly shorter on the Trybe barrel. The forward lug is also offset slightly forward. Since I've cut this to length, I can't return it. When I was able to chamber a round, the bullet did come out of the barrel when I pulled the trigger, so that part was OK. :)

These barrels should work in a G21 setup, but for some reason this one doesn't. It may have worked OK in a G20. Since that was not my application I can't properly rate it, so I'm giving it a neutral 3/5 stars.
