Mark is a great guy to deal with, very busy guy but answered my calls ASAP.
I recently purchased one of the S&W 5906's he has listed on his website.
Yesterday I ran 400 rounds (mixed WWWB Magtech & Some ATK JHP) through the pistol..
I had 3 FTF... but that was with some pretty funky looking JHP in the last 15 round magazine I shot...
!! THUMBS UP !!
