Your Questions Answered
Is this a true drop-in barrel, or will it need fitting?
Based on our testing with multiple Gen 3, 4, and 5 frames, this is a true drop-in barrel. We have not encountered a frame that required fitting. Install it, function check, and you’re ready to go.
Does the threaded end come with a protector or thread adapter?
No, this barrel ships as shown. The threaded muzzle (1/2×28) is unprotected. You will need to source your own thread protector or direct-thread muzzle device separately.
Will this barrel cycle +P or +P+ ammunition?
It is constructed from 4140 steel and has a fully supported chamber, which is suitable for standard pressure and +P 9mm ammunition. We do not recommend sustained use of +P+ ammunition, as it exceeds SAAMI specifications.
