I posted a while ago about my agency’s experience with 43 mags. We are all issued a 43 as a bug. Every time we shoot quals I see plenty of malfunctions up and down the line. 24 different guns with every manner of extension on the market. None work reliably. So far the “best” has been the 9 round ETS magazine. They generally feed reliably, but fail to lock my slide back over 50% of the time. I will only carry and recommend factory 6 round mags for carry.
I think the “A” answer would be for them to scrap the 43 as is, and just make a shorter grip 43x. But I doubt that ever happens.
