Product reviews: Mec-Gar Beretta 96 .40S&W 15rd magazine - ANTI-FRICTION COATING W/ADAPTER

First of all, working with the people at Top Gun was great. And the quality/workmanship of the Mec-Gar 15 rd magazine was great. But... was only able to award 3 stars. Where they (Mec-Gar) missed the mark was that I had a nearly 100% jam rate when hand cycling the slide with hollow point ammo (JHP). Upon closer inspection, I measured the opening at the top of the magazine and found them (all 4 of them) about 0.9mm narrower than the factory Beretta Mags. Beretta mags measured 9.6-9.9mm(2x) vs. Mec-Gar 8.9-9.0mm (4x measured). This, in turn, meant that the rounds were lower down the feed ramp; causing the sharp edge of the JHP to catch on the feed-ramp bottom (jamming). The guys at Top Gun immediately offered to take them back; but, I refused the offer; instead, I was able to insert some heavy duty ring lock pliers at the top, and flare the openings about 0.5 to 0.8mm. They now work flawlessly. The front of the bullet is angled a bit higher. Due to the sheetmetal wrap-around at the back end, was not possible to flare along entire length; but, feed just fine. Would have been tempted to return, but really wanted the capacity, and the workmanship of Mec-Gar (obviously, above issued excluded)
