Title: Folding Stock Solution For The MP, 1377, & 2240
Post by: airgunenthusiast on December 17, 2010, 12:10:57 AM
I began altering Crosman pistol grip frames (1377C & 2240) to receive folding stocks about 3 months ago.  I've made a few of these sets now and they work very well.  The folding stock takes just seconds to install or remove and can be folded or unfolded just a quickly.  It doesn't add much length to the pistol and when folded improves the balance in pistol configuration.  The adapter sets I've produced so far are for the old 2 screw style Crosman grip frames.  I'll have to make a slightly different adapter set for my Marauder pistol's new style 3 screw grip frame though.  I fitted this 1377C frame to my MP just to see how it looked and handled.  

I'll make a matching laminated forestock for the MP once I can get my hands on an extra 3 screw frame to go with it.  I want to leave the original MP frame unaltered for now.  I'm consider making a few adapter sets available for purchase too.

LOVE IT!

Price? What has to be done to the frame to accept it?

It would really depend on the final configuration and what pistol it will be used with. 
Standard plastic grips won't fit without alteration (removal of material).  Wooden grips made by other custom makers would need alteration as well.  The alteration to the grip panels isn't rocket science but would have to be done to accept the actual frame & adapter for the metal stock.  So if someone wanted to purchase an altered grip frame with the adapter fitted to it's base, the folding metal stock, and custom fitted laminated grip panels with a matching forestock the price would likely be in the $225 to $250 range.  If someone wanted to make their own grip panels and forestock the price would be less.

Altering the grip frame consists of drilling a small precisely located hole into it's base and cutting a shallow but accurately positioned groove into the back of the frame.

To fit factory grip panels one would need to shorten their length and cut a precise notch into the left panel's base.

Here are some more pics:

Dan,
This is a great design!
Excellent work, I'm very impressed ......
Any pics of how the folding stock is fixed to the trigger frame grip base.

Regards
Ian

Hi,
Newbie here but I felt I had to comment.  I read the review on the Maurader Pistol and It commented on the screw that is forward and above the trigger.  is this the third screw you are referring to?.  I just received my 1377C ordered from Pyramid Air and it has that same screw on it.  It appears this might be a new mod to the 1377C.  I like the grip on your gun and the folding stock.

Great Video and Super Cool Stock. Are these going to be available for purchase? If so, I would be interested in one of your first offs.
Cool stuff.  :-*   :-*   :-*
