Anybody using the subject sight? Purchased my Spectrum a few days before Christmas, but just got around to shooting it today for the 1st time. Ran some 20 years old ammo through it w/o a single hiccup (PMC Target & CCI Blazer w/ aluminum shells). The Veridian looks like a nice factory-like installation that shouldn't mar the gun's finish & good reviews. Just want thoughts from others on here.
