This Grayguns-branded, Springer Precision SIG SAUER® P320 Extended Capacity Basepad extends the length of the magazine to allow for extra round capacity and easier magazine exchanges while meeting the maximum length* (140mm) for USPSA Limited and Carry Optics divisions. These basepads have proven to be popular with competition shooters.
CNC machined from aluminum and hard anodized for a long service life.
Includes extra power replacement magazine spring.
A .050 hex driver (included) is required for installation. You may need to remove some material from the magazine rail to set the hex screw. This can easily be accomplished with a small file.
Important note: This basepad is specifically for 9mm or .40 S&W P320 magazines. Extra capacity varies depending on ammunition caliber.
* As with all competition geared changes, ensure you test and check your gear before your match. With our 140mm Extended Capacity Basepad, verify the magazine fits the USPSA gauge. OEM magazine length varies from the factory, and we don’t want you to hear the phrase “Welcome to the Open Division” during gear inspection.
