As much as I want to like the gun, I love my Q5, shooters who put a lot of rounds through them are having problems with the triggers getting heavier and grittier with use. I also on theory, do not like there optics cut. These two things have kept me from purchasing the gun.
Interesting that your trigger is getting heavier, any idea as to the cause? Also the PDP optics cut seems totally solid at this point (albeit slightly different than some other options) the Sage Dynamics video posted above Aaron drops the PDP from shoulder height 5 times over the course of a 2,000 round review with no issues.
