Good call. I have tossed this idea around as well. Purchase the 9mm mags and get the gun itself later on. I haven't looked too much yet, but I'm guessing the 17 round mags are probably gone everywhere too just like glock mags.Quote:
Best bet is to just get the magazines you want now - if you can find them - and hope they do not incorporate semi-auto pistols, like the M&P series. I'd also consider the compact M&P since it will support the short mag and full size mag. You can even get the x-grip extension so the mag doesn't stick out. With full mag, the main difference will be barrel length.
