First off I will say that I am glad to see that us palm continues to be innovative. That being said, this has little use to me. I own a couple of 40 rnd mags. It is always hard to figure worth. Mag changes are not that hard to do, and with only 10-15 extra rounds over standard mags you are still going to be changing mags (if you actually have to pop of 45 rnds there may be a good chance that you might need more). Would these be better, probably, but It all depends on how fat they end up being. The 40s are long which sucks, but if these end up being too fat they could have there own issues with handleing as well. In the end, it is too early to tell. Still, it is probably worth buying one or two.
