You ought to get the mrs. a set of Crimson Trace grips for that AirLite. Put the dot on the bad guy.
Since most of her “risky time” is hiking in the wilderness, the Hi-Viz is probably better.
I am not a fan of laser grips for several reasons. The biggest one is a tendency to “chase the dot” because it moves a fair bit, and I’ve seen many people at the range, try to snap off a shot as it swings across the target.
If it’s dark, I have a 500 lumen strobing light and a 16 gauge Winchester M12 full of #1 buck.
