Red dot fpr pistol

[ambishooter]

I have a Shadow 1 running a Sig Romeo 1 for about 4 years, so far no issue other than a slight zero drift after over 1000 rds. Could be the mounting screw. Reinforced the screw with blue thread locker, so far, so good. Since then, I am looking to put another red dot on my other pistol, an 85 Combat. This is my backup pistol, and I am looking at these low cost candidates under $ 300:

Bushnell RXU-200 1x21mm Ultra-Compact FMC 6 MOA -SHIELD RMSc Footprint 5-year Warranty ??? maybe lifetime?
PRIMARY ARMS SLX RS-10 1X23MM MINI REFLEX SIGHT - Docter Footprint - Lifetime Warranty
VORTEX VIPER RED DOT - Docter Footprint - 6 MOA Lifetime Warranty

Any idea which might be a better option among the 3 listed above? Is there a SHIELD RMSc Footprint available for a non-Optic Ready CZ 85 Combat? It seems like a Docter Footprint is more popularly available for CZ Pistols.

Holosun 407k or 507k would be a better option

If you go Vortex get the Venom not the Viper, Venom is a top loader for battery, Viper loads in the bottom so must be removed and re sighted if and when you change the battery. I’ve had excellent service from 4 different Venoms on handguns and I shoot a lot and bash them around pretty good lol. I’ve got a couple of Holosuns also and they are a fantastic option, but RMR footprint

Thanks for the inputs. Now, the next step is to find a suitable mount for my non-optic ready pistols. My Sig Romeo 1 is already installed, not an issue moving to either pistols. Having the options of the Vortex Venom or Holosun 407, who has either of these mount in Canada for my SPO1 Shadowline and 85 Combat? Is there a standard mount for these pistols for either of the mentioned red dots?

I'll tag in on this as I'd like to put a red dot on my 85C as well.
