All I know is it had that silly tip up barrel feature which I never understood
That feature is actually really awesome. The main spring can be really stiff and there isn't a lot of real estate to purchase when trying to rack. The tip up barrel allows you to load the pistol so you don't have to rack the slide. I have a Beretta 21A pretty similar except for the trigger.
It likes high velocity ammo. Velocitors and mini mags. You need some umph since it is a blowback with no extractor.
