I’m using them in my 43x and love them. The two that I have have functioned flawlessly.
Just curious: Do you use an aluminum magazine release as recommended? If not, do you notice any wear on your factory polymer one from the use of the metal mag?
I've got about 350 or so rounds through my 43x using Shield Arms magazines. No hiccups or bobbles so far. I did change out to a metal mag catch. I had friends who had trouble keeping magazines in their Smith and Wesson M&P pistols (The 1.0 version) when our F&W issued them some years back. Turned out the plastic mag catches were wearing out.
