Frequently Asked Questions
Will this barrel work with my standard Glock 23 magazines and slide?
Yes — when converting from .40 S&W to 9mm using this Rival Arms barrel, you will need to use 9mm magazines (such as those from a Glock 19) since 9mm cartridges will not feed reliably from .40 S&W magazines. Your existing Glock 23 slide, frame, and extractor are generally compatible, though some shooters opt to swap the extractor for optimal reliability with 9mm. No modifications to the frame are required for the barrel itself.
What suppressor thread pitch does this barrel use, and is a thread protector included?
This Rival Arms threaded barrel uses the industry-standard 1/2-28 right-hand thread pitch, which is compatible with the vast majority of 9mm suppressors, compensators, and muzzle devices on the market. A thread protector is included to safeguard the threads when shooting unsuppressed.
How does the BORSLICK Boron Nitride coating improve performance over a standard barrel?
BORSLICK Boron Nitride DCD (Dynamic Compound Deposit) is an ultra-hard, low-friction coating applied at the molecular level to the bore and exterior surfaces. It significantly reduces fouling buildup, makes cleaning easier, and extends the service life of the barrel compared to standard phosphate or uncoated finishes. Combined with the low-temperature vacuum PVD outer coating, the result is a barrel that stays cleaner longer and performs consistently through thousands of rounds.
