Hi Dave. I'm using M-Pro 7 & it's lubed sufficiently. I can see the frame in the dust cover area is not machined perfectly round. And to reiterate, I haven't even fired it yet. I've prob racked the slide about 50x so far with snap caps, or slowly released without snap caps. I find this unacceptable for a $1350 pistol.
