I realize this is very hard to diagnose, but hey, I'll take a shot at it. I took apart my 952 to give it good cleaning. I did not remove the barrel or spring from the slide, I just remove the slide assembly from the frame and that's it. Replacing the slide everything seemed normal after replacing the slide stop but the slide will not go all the way forward. It was difficult but I did get the slide stop back out. With some effort I can get the slide to go all the way back but trying to go forward it stops with about an inch of barrel still protruding. Anyone have any thoughts or need more description? I'm really embarrassed to go to a smith and ask for help plus the gun is not that common so they may not be familiar with it. I do have another one I could take with me for them to look at, but like I said, really embarrassing.
