Wardog,
As suggested, go ahead and clean the gun, then try it again. If that doesn't work, give Maria a call. They take misfires pretty seriously! I just went through this with a new R-9 Stealth. When clean, it would seem to work fine for a mag or two. After that, I could figure on at least one misfire per mag.
In talking with Karl, apparently there was a small lot of defective hammers produced. It is possible you have one of those. FWIW, the turnaround on my gun was about 10 days.
Good Luck
