it's hard to call this anything other than a full-size gun.
Yes, I could have chosen better words than "full size",,,
But the intent was to differentiate between single-action target pistols,,,
And those pistols that are the same size and action type as many duty weapons in use.
While the Rugers, Brownings, Beretta's, and S&W 22A are fine pistols,,,
They do not emulate/duplicate the manual of arms of a duty gun.
Now I'm waiting for someone to jump up say,,,
The 22/45 emulates a 1911.
The OP's words were "large full size",,,
I'm just using the same terminology he used.
