Product Notes

  • UPSPA Length – The 17-round magazines with our +5 base pads will fit the 141.25 mm size limit for Limited and Carry Optics
  • No base plate is required as the back plate (shown) is used to hold the base pad in place.
  • The last round is pretty tough to load on the 17-round magazines, we suggest you use a loader. The 15 and 21-round magazines are easier to fully load.
  • These aluminum base pads weigh 1.2 ounces.

    just purchased several new GG base plates for my P320’s, i had put on extended magwell’s on my Sig’s and have been wanting these plates to personalize and make them more functional and they installed in minutes and feel and look great and they work flawlessly with my 320’s, could not be happier and will be buying new triggers next … thanks for following up Bruce

    Perfect weight, quality construction, sleek design, durable, and the laser marking is a cheap add-on. Some machine marks, but nothing to fret about. They shipped fast! I ordered on a Friday and they made it to me by the following Wednesday (Oregon to Chicago), in time for me to use for my weekly shoot night! GrayGuns is doing amazing work over there!!

    I purchased the mag extension for my Sig XCarry’s 3 stock 17rd mags and a 21rd mag. The build quality is great! Very heavy duty,and they came with new springs to accommodate the change. Thanks Gray Guns!
