Update … I’m no longer carrying my 43 with the shield arms mag. After testing, my 43’s slide would lock back with one round left in the magazine. I’m sending it back to shield arms for them to look at. I was hoping they would just exchange it for me but nope, they make it hard by insisting they test my mag and determine next steps. That’s annoying customer service. Especially for a return customer like me.
Shield Arms, the same company that released 15 rounds magazines for the Glock 43x, just released a 9 round round magazine for the Glock 43. They achieve this with adding very little length to the group. My Glock 43 had been a safe queen since I was able carry my 43x with 15 rounds. But now with a 9+1 option I think my Glock 43 will be back in the rotation, especially in the summer. I ordered one of the magazines from shield arms and will run a couple 100 rounds before I start carrying it. The magazines I have bought from them for my Glock 43x have been flawless. Hopefully these will be too.
