what's the most affordable red dot that will work? It's the CP33, the one Kel Tec came out with, so it's not on a slide that moves, which should reduce stress on the optic, thus I don't feel top of the line is necessary for a red dot. https://www.amazon.com/Feyachi-Refl...8&s=gateway&sprefix=mini+refle,aps,130&sr=8-8 How about this one? It's got a lot of reviews and is cheap. Feyachi... I can't tell if that's Italian or Japanese, so it must be good!
