FAQ
Will this fit my Glock 19 Gen 5 with a factory threaded barrel?
Yes. If your factory or aftermarket Glock barrel for 9mm or .357 SIG has the standard 1/2″x28 thread pattern, this protector will fit correctly. Always verify your barrel’s thread specification before purchase.
How do I prevent the thread protector from loosening during firing?
For a secure fit, we recommend applying a small amount of witness-markable thread sealant (like Vibratite VC3) or a thin o-ring on the barrel threads before screwing on the protector. This provides resistance against vibration while still allowing for removal with hand tools.
