I recently bought a Mec-Gar 13rd magazine for my XD .40 subcompact and had multiple failure to feed issues today at the range. I initially thought it was just through my gun however it continued to have issues when used I'm my wife's XD as well as a fellow shooters. I am wondering if anyone else had any issues of this nature. I have yet to ever have a single issue when using OEM magazines. The magazine appears to be different than a springfield one and I believe there may be a design flaw. I did receive a refund and was prompted to retain or destroy my magazine. Why wasn't I even offered a replacement? Maybe this is a known issue? The magazine is made very well and durable.
