Yes that is a downside with the TF. But I will say that I ran them for probably a year and only had to clean my mags once in that time! How's that for reliability?! That's something that my new Caspian's mags won't even think about doing. One little grain of sand will lock them up tight, so if you drop one in the dirt, you ARE brushing it. No if's, and's or but's about it. :angry:
That's my only gripe with that gun. M&P's will just spoil you...
