I have a mini socom with the extreemly gripy inserts and the frame lock. I have recently acquired an intrest in the full size version aswell, but have generally only seen them with rubber inserts and a liner type lock. I think I saw a full sized model with the gripy inserts, but it was an auto. -Have they made a large manual without the rubber and is it a liner lock, or frame lock? Are they pretty rare? Thanks for the help.
