I believe in the KISS - Keep It Simple, Stupid - principle, but sometimes new tech is good.
I like the Crimson Trace grips on my S&W 340Sc - aside from the red dot being easier to pick up than the itty bitty sights on this little gun, they also help to practice "point shooting" at home as well. (Usual safety disclaimers apply.)
I got a weapon light for my AR . . . at a gun show a vendor tried to sell me one with about 12 different modes of operation - bright, low level, focus, no focus, various strobes, etc. Uh-uh. I ended up getting a simple SureFire with a simple "on-off" button on the tailcap.
As for this Tracking Point 'scope . . . it seems pretty expensive to get, essentially, a "do over" since you have to designate your target once, verify that you've designated it correctly, and then aim again to shoot. The ballistic computer sounds neat if it really, really will accurately compensate for conditions, target movement, etc., but what seems to be lacking in the reports I've seen is actual group size at long range produced by the system.
