Sig P320 9/40 extended base pads 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. 0.80 OZ Not reccommended for use with P320 X5 magwell 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)
Perfect addition
Was looking for a more durable magazine base plate and boy oh boy did I find it! These are awesome and work perfectly with my grip module. I can’t imagine having to ever replace them, unless I lose them in a canoe accident.
