...while i will stick with Glock magazines, i did pick one of these up awhile back to give it a go.
so far, it has functioned flawlessly...
potential "con";
wife felt that it was a little more difficult for her to load, as contrasted to loading the various Glock magazines...
potential "pros";
a. the base pad is definitely much easier to remove for disassembly. while some might view that as a possible negative, i surely don't...
b. as seen in the pic, the base pad sits at nearly 90 degrees to the axis of the body. if a chap is using a mag loading device (which i rarely use), when resting it on a table the mag will orient to nearly vertical, as opposed to the glock, which sits at somewhat of an awkward angle when using the mag loader in that manner.
