I have handguns with a fixed 2.5, a 2-6 variable and a reddot and used them all a bunch. The reddot is on my Ruger SBHH and I think that is the ideal sighting arrangement for that rig. My 69 year old eyes have no problem placing accurate shots out to 100 yards what I consider a maximum hunting range for a revolver. When I first got the rig last year it put 5 out of 5 shots on the 14 inch steel plate we have hanging at 200 yards.
The reddot really shines at dawn and dusk, much better then my scopes.

My variable is on a 14 inch contender in 308 Bellm and the extra power is definately usable on a rig that will reach out and touch game at 200+ yards.
