does it have a safety and does it lock open

Frank - There is a manual 'thumb' safety on this pistol, and it does have the 'hold open' feature after last round in mag is fired, so slide will stay open.

yes it has a last round hold open and also has a manual safety

Frank, yes Sir. This Taurus G2C does have a "Manual Safety" and the slide does lock back on the last round fired.
