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.
