Just a PSA (pun intended) if you wear size large gloves or larger, pull the baseplate(s) off and break/round the top back corner on the plate (the rearmost part where it slides onto the mag body and just below the grip) or it'll bite you when you when practicing mag changes.
If you've got really meaty or fleshy hands it may get you anyways. You don't need to take off much, just a minute or two of rounding and smoothing with some fine sandpaper does the job but as they come that corner has a point that'll pinch.
Just my experience so far; now that my extra mags came in I need to get it to the range.
