Extended basepads for Sig Sauer P320 .45 are CNC machined from aluminum and hard anodized. This lengthens the magazine .375" to make for easier, more reliable magazine changes. They also allow you to use a magwell without adding capacity to the magazines. They are perfect for IDPA ESP and USPSA.

*New magazines have a square-style locking floortab/basepad.  If you have this style (as opposed to the round nipple-style locking floortab) please select the appropriate option in the drop-down menu.  (see picture)

Due to design variations, Springer Precision cannot guarantee compatibility with any other manufacturer’s aftermarket magwell, unless otherwise specified. Please email us with any questions.
