  1. 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.

  2. Converting old P320 Mags

    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.

    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

  6. Perfect Fit

    Baseplates went on easy and fir perfect. If you own a compact you will really like these as the baseplate contours with the grip.
