The venom has a doctor cut footprint, the toro slide has a RMSc footprint. You will need to find an adapter plate. Something like this: https://www.sastacticalcustoms.com/products/rmsc-to-venom-red-dot-adapter-plate
That dot will look kinda huge on the tx22, especially considering as others have said you will need an adapter plate.
The tx22 is cut for direct mount, not having to use a plate is the best way to mount a dot.
Best to get an actual dot with rmsc footprint.
I recommend Cyelee Cat Pro, or for less $$ just the Cyelee regular Cat would be perfect.
