Finally had a chance to try the small grip module on my 320C RX today. Since I'll be carrying the 320 I sighted it in at a more realistic five to seven yards and found I was shooting an inch or two low. I still need to work with the red dot as I ran out of time but was pretty close to point of aim with the red dot close to the middle of the white dot on the front sight. This seems pretty low to me, was wondering if others also wound up with the red dot low on the front sight.
