P320 9/40 +10 Magazine Extension
This basepad is designed for us with the stock 17 round magazines. A longer extra power spring must be sourced in order to use with the 21 round magazines.
Springer Precision Sig P320 9mm +10 extended capacity base pads are CNC machined from aluminum and hard anodized for a long service life. We provide the option to get them with a Grams Engineering follower kit for maximum capacity, or with a regular extra power spring to use with your follower. The unique locking mechanism allows a very solid attachment with a simple backing out of the discrete set screw. They are specifically designed to work with our mag wells. The unique attachment design provides a low profile, sleek design that is very stable and easy to remove. * We include a .050 hex driver that makes installation and removal a breeze. There will be a gap between the base pad and frame if used with a compact model. 2.474oz
*slide lockback funtionality disabled when using Grams Follower kit*
*works on .40, will not be +10. Capacity should be closer to +8
**Disclaimer: As with all competition geared changes, always make sure you test and check your gear before you take it to a competition setting. With 140mm/170mm magazine configurations especially, check the magazine in a USPSA 140mm/170mm gauge to make sure it fits. With mass produced items like magazines, sometimes they can vary slightly from one to the next, often in the magazine lips that connect with the magazine extension/basepad.
Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. Please call us with any questions.
