Springer Precision extended basepads for Sig Sauer P320 9/40 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. Perfect for use with Sig P320 X5 with or without the factory magwell.

.76 OZ 

Custom engraved and custom colors are non-returnable.

*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)

*Not for the 21rd 9mm/18rd .40 factory mags, please see SP0218 for a basepad for those mags.

*Not compatible with flanges that fold into the magazine body (P250, P320 Subcompact 12rd).*

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.
