  1. Perfect

    Kept having issues with my les baer using the factory mags. Cleaned my gun and Switched to these and finally had a range session with zero failures. If you’re having issues with a baer give these a fair shot. (Pun intended)

  2. Tripp research 8 rd .45 1911 magazine

    Posted by Unknown on Apr 21st 2020

    I purchased an 8rd and 2 10rd Tripp magazines a couple of months ago. These are my absolute favorite and from here forward, the only 1911 mags I will purchase. Perfect feeding, smooth follower movement and stout mag bodies. I liked them so much I bought Tripp super 7 kits for all of my other 1911 mags. Dawson has the best stuff!

  3. Outstanding mag

    I had 2 for few months, bought 2 more this time around. Super reliable. Very well built. Great fit and finish. Works great in the 1911s (Kimber, Colt and Llama) I've used it in.
    Very happy with it. Highly recommended.

  4. Great Mag

    Tripp Research magazines are best on market for my 1911. Have been using them for many years and will continue. Dawson Precision only sells best quality products.

    Flawless fit, finish and performance. Never a FTF or FTE. The hybrid follower is unique and assures a positive load and feed. Simply the best SS mag on the market whether for EDC or competition.
