Can anyone recommend a good scope or red dot sight for a beretta cx4 in 9mm? I have no clue about optics at all

Thanks in advance

I have to look at mine, but I am pretty sure it is a cheap BSA from Amazon, Red & Green Dot, but I only use the Green portion. Co-witnesses with the stock sights, IE: Turn the optic off and you can still use the stock sights. Plus, to zero the optic, just get the dot to line-up with the stock sights. I use this gun for Knockdown Steel every month, that cheap dot has been perfect!

Bushnell TRS-25...

 

Have one its great.

I use a Vortex Sparc on mine, with a lower 1/3 cowitness. It comes with mounting hardware and a screw-in 2x maginifier.

I use the vortex sparc on mine as well.

Another vote for the vortex sparc.

how much you want to spend is the real question.

Burris XTS-135. Burris is made by Beretta.

vortex minus the magnifier, great weapon mines digest everything. Good luck with yours.

I have some little $35 reflex red dot on mine and it works fabulously.
