My friend Michael Grasso was able to obtain a loaner RMR HD from Trijicon to use on the Staccato C test pistol. There's some question as to whether the fact that the element slightly overhanging the rear edge of the ejection port would affect the reliable ejection of spent cases or not.
I was optimistic, since I've put thousands of rounds through several FN509's wearing a Trijicon SRO, which similarly overhangs the rear of the ejection port, without any problems.
We mounted the optic, got it dialed in, and proceeded to crank out two hundred rounds at a pace that left the slide hot enough to be painful to the touch. Not only were there no malfunctions of any type, the brass does not seem to contact the sight housing at all.
This morning I'll get back to the range and we'll try some different brands of ammunition with varying power factors.
