A special warning:
Do NOT trust the safety as far as carrying a chambered round. The safety mechanism is prone to failure and if pistol is dropped, it may discharge. This happened to me.
Others have reported if a round is chambered with the safety on and you squeeze the trigger hard enough the pistol will fire. I've not tried this
As far as being safe to shoot? Can't answer that question on your specific pistol. No way of knowing its condition.
I've had two of them for many years. Used to shoot the snot out of both. As long as I kept them relatively clean they fired CCI Stingers and Rem. .22 ammo quite well.
