Anyone else had a problem getting 8 rounds in the M&P flush mag. The one with the finger extension was no problem, but even with an UpLULA I could only manage 7 in the flush baseplate mag. I've had new tight mags before, but not this tight.
Yes I realize that only the base plate is different. I was just differentiating. I've loaded 7 rounds in the problem mag, and hope that it will loosen over time. I've had dozens of new mags and this is the first time the UpLULA couldn't load the mag fully. I did disassemble it, but noticed no burrs or anything else unusual.
