I don't count specifically, but based on practice schedule over the past couple years I have:
~30,000 rounds through my range M&P9 (Maybe three or four malfunctions that weren't directly ammo related - ie: bad Winclean primers)
~20,000 -25,000 rounds through my personal Beretta 92FS (2 malfunctions - one stovepipe and one failure to extract)
~ 5,000 - 6,000 rounds through my issued (now purchased) Beretta 92FS (No malfunctions)
~ 6,000 - 8,000 rounds through my personal M&P9 (One non-ammo fail to extract and one or two stovepipes)
~ 3,000 - 4,000 rounds through my issued M&P9 (No malfunctions)
~ 1,500 rounds or so through my M&P9C (One or two early fail to extracts...Since then it's been 100% reliable).
I strongly feel several of the malfunctions, especially the stovepipes, were the direct result of Winclean ammunition, or (especially in the case of my personal Beretta, personal M&P, and range M&P) failure to properly maintain. Because the above firearms were not used at the time for duty or off-duty I simply abused them. I used my personal M&P from September 2011 through December 2011 (about 5,000 rounds) without any cleaning OR lubrication. None. I cleaned and lubed it after we were issued our range guns in December.
I haven't shot nearly as much this year (since November) due to a bad case of tennis elbow, but I've been shooting my issued M&P almost exclusively with Federal 124gr American Eagle and it has been 100% since late December of last year.
