I recently inherited this semi-auto hand gun from my grandpa. Before I do anything w/ it, I was wondering if there's anyone here that has any familiarity w/ it. My first issue is, last night I was just looking it over. When I pulled the slide back, it slid right off (cutting the crap out of the palm of my hand). I watched a youtube video on dis-assembly/field strip takedown, but the version in the video I found is a little different than mine. My version has the lever on the back upper side of the gun that you press down on and it has the longer barrel. Can anyone here help me begin to asses the working condition of this gun? My grandpa actually gave me 3 of his guns and I considered selling this one for different 22, but after reading up on these I guess they're pretty decent. At this point, I'd like to learn more about upkeep and if or how to fix the slide.
