Affordable reflex sight.

I had the Bushnell TRS-25 on a Browning Buckmark but wasn't all that impressed, even though the reviews rave about the sight. I prefer this style and have half a dozen or so of them. https://www.midwayusa.com/product/13129 ... ount-matte

I went with the Vortex Strike fire, for now. It's an Aimpoint clone, more or less, has no paralax at 50 yds, has 2 hour auto off, NV compatible, 11 brightness settings, and red/green dot, and a lifetime warranty. I doubt that it's a combat optic, but for range work, it's more than adequate.
I took mine out last week, and was nailing a Copenhagen lid at 100 yds.
They are a site sponsor here, and VortexSam seems to be a standup guy, and quite helpful.

They only complaint I have heard, is location of the power button, outside of that they seem to be GTG, for $150.
