The guy at the gunstore said he would pick a mark3 over a .22 wheelgun anytime because the old revolver technology just cant keep up with pistols,
The guy at the gun store is not giving you anything,,,
Except his own personal opinion,,,
A sad one at that.
Comparing revolver technology with semi-auto technology is a non sequitur,,,
The two do not compare at all.
I would bet money that if one were to put those two handguns in a Ransom Rest,,,
The difference in accuracy would be negligible if at all.
They are both Rugers so they are built strong like tanks,,,
If you want the ability to shoot special ammo,,,
Get the revolver and don't look back.
