Whether you're setting up in Pleasanton or anywhere in Northern California, TacticCAL handles FFL transfer in Sunnyvale with straightforward service and no surprises.

Compensated Barrel Design and Function

The integrated compensator redirects gas to reduce muzzle rise during rapid fire. This design improves shot-to-shot speed without requiring a separate comp purchase or slide modifications. The 4.5-inch length balances velocity retention with manageability in compact frames. Installation follows standard Glock barrel swap procedures—no gunsmithing required. Check our California-compliant handgun catalog for compatible slides and parts that pair well with threaded barrels. TacticCAL is your local gun shop in the Bay Area.
