Your Questions Answered
Is this a true drop-in barrel?
Yes. Our staff has installed this barrel on multiple OEM and aftermarket Glock 17 frames. No fitting, filing, or gunsmithing was required for proper function in our tests.
What muzzle devices fit the Python thread?
The Python thread (M13.5×1 LH) is a common pattern. Many compensators and thread protectors are made for it. Ensure any device you purchase specifies compatibility with M13.5×1 LH or “Python” threading.
Will this work with my Polymer80 or other 80% frame?
It is designed for the Glock 17 platform. We have successfully tested it in several completed Polymer80 PF940v2 frames. As with any aftermarket part, function should be verified with your specific build and ammunition.
