I have 2 A1 Optics 4 MOA red dots and one TruGlo 5 MOA. I like the A1 Optic better....smaller dot. All seem to stand up well to recoil on the pistol caliber Handis. Real easy to use. Keep both eyes open, and target acquisition is immediate. I got the A1s from a guy on ebay.....only 39.95 free shipping. Search A1 Optic. Some guys here sight them in so point of impact is at the bottom or top of the dot. That way, the dot doesn't cover a small target. Good luck.

I forgot to mention, mount them forward on the scope mount or scout mount them. Eye relief is unlimited, and you can put away your hammer spur. No hammer clearance problem.
