Correction to my earlier post in this thread. One of my kimbers has become touchy with ed brown magazines. My govt sized kimber doesnt care, but my Pro is not 100% reliable. As I did some loading and unloading of the different magazines I found the Ed Browns, both in 7 round and 8 round, were not liking the final round loaded or in other words the top round. It gets extremely bound up with friction and feeds the round nose low. The Kimber Pro tac-mags load and feed super well. I bought two of them locally, tried them through different brands of 230gr ball and after 200 rounds they proved to be absolutely reliable and even the first round sounded smoother (compared to my ed browns) as the slide ran forward.
I also reached out to Tripp and purchased a flush 7 rounder. It came in today. I’ll test its feed and reliability this weekend, but this magazine is top notch. It even feels a little heavier. The follower is perfectly smooth, anti-tilt, no seams from welding. It is an absolutely top tier product.
Also through my research of magazines I learned to watch out for certain followers if you have alloy frames. While my alloy frame is old and already “broke-in”, i want to prevent any more destruction to the best of my ability. Chips Power Mag Plus has a well written description of why you want certain followers on their website.
