CO2 blow back pellet or BB pistol

[Reuben]

I am thinking about buying a couple of co2 pistols to target shoot in my back yard…
Preferably replica’s of famous military hand guns…

If anyone has experience and recommendations I surely would appreciate it…thanks

I practice with 22’s in browning buckmark and the Ruger mark4 hunter…

But I would like to shoot more often so looking at the CO2’s…
