Sig 320 base pas
I put them on my old style compact mags and use them for IDPA With my 320 X Compact. They work great and the extra weight and length are great.
Description
These extended baseplates are CNC machined from billet aluminum and uniquely designed to ease the installation and removal of the baseplate to the mag body. In addition, they DO NOT ADD CAPACITY and each weigh 1 oz., making them legal for USPSA®, IDPA, and IPSC® competition*. And, of course, the taller baseplates also help facilitate reloads when using a magwell.
*After installation, check to ensure that your gun still fits the appropriate box as guns vary dimensionally.
DISCLAIMER: This WILL NOT FIT Sig Sauer® P320® Compact magazines.

I put them on my old style compact mags and use them for IDPA With my 320 X Compact. They work great and the extra weight and length are great.
I purchased a new P320 X-Carry. It came with three (3) new style mags. Meanwhile I had on hand two P320 mags from that wasn't compatible with the new P320 X-Carry without modification or adapting a new base plate. I ordered new base plates from Dawson Precision. After receiving the Dawson base plates, I removed the old ones and slipped on the Dawson base plates. I shot the P320 X-Carry yesterday and it worked great with the new base plates from Dawson Precision.
Feels great in the hand. Looks solid and made of great material.
Adds a perfect balance to it. And fits great
I bought three of these for my production rig, and really like them. The extra weight helps reloads, and the length helped to grab and seat them, compared to the stockers. I wish they were designed to fit into the notch on the grip module better, but really a very "minor" (IPSC joke) concern. Buy with confidence
Baseplates went on easy and fir perfect. If you own a compact you will really like these as the baseplate contours with the grip.
