Be careful with the recoil assembly. I'll tell you a funny story (not funny at the time)...
A couple of years ago, I picked up a VIS35. I did a detail clean, down to taking apart the recoil guide assembly. I was working in an area that was unusually high in clutter (half open boxes, papers, tools). When reassembling the recoil guide, I compressed the guide and lost my grip on it... launching the rear section (part# 11) across the room.
I heard the piece hit the window pane. No problem... must be somewhere near the bottom of the window (you know, gravity). Found the small, captive spring right away... but the much larger rear section is GONE! Searched the boxes under the window. Where could it have slipped? Searched in an ever increasing arc away from the window. How far could it have bounced?
After about 1 hour and much profanity, I finally found it. It hit the window and dropped directly into the cup of the thumb-turn window lock (neatly camouflaged in color I add).
It probably would have hurt if it hit me in the eye.
That's when I got the bright idea to use a vise to neatly and securely compress the assembly while inserting the pin (part# 7). Worked like a charm.
