Optics for 12.5" pistol??

[VASCAR2]

I’m using a Vortex Strike Eagle 1-6 but I have also used an old 2.5-10x42 Japanese manufactured Tasco scope with duplex reticle. I like the higher magnification for varmint hunting and shooting small groups on paper targets. For a gun that could be used for self defense or close range hunting red dot sights and low power variable optics work well for me.
