.25" Basepad Square Hole for Sig Sauer P320


Springer Precision extended basepads for Sig Sauer P320 9/40 are CNC machined from aluminum and hard anodized. This lengthens the magazine .25" 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.

Custom engraved and custom colors are non-returnable.

*Not reccommended for use with P320 X5 Open/LTD magwells as they will be recessed. 

*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 call us with any questions.
