Need help! 2289 backpacker stock internals (spring and pin) photo anyone?

[cshooter]

Is anyone has or can made 2289 backpacker fast detach stock internals (spring and pin) and how they are placed together? As I understand right it's easy to mod "standard stock" to this feature but it's hard to imagine how it's put together without pics.

Thank You guys!

Here is alink  to a close up of it. Notice that there are no grip screws. The pin protrudes down through the hole in the grip frame at the back of the frame and holds the rear of the grip forward against the frame. There is a spring on top of the pin and is held in place by the tube and a  counter bore in the pin. Hope this makes sense. Search for more pics. I know there is a better pic somewhere on here. But I could not find it.

Thank You for replay! At least now I know where this pin is placed, as before I think that it is something inside stock.

To install stock detent pin & spring:

Remove gripframe from pump tube in an upright position. This will help keep from losing safety spring and ball.
Drop stock dentent pin into it's location followed by dentent pin spring.

Note that normally, as Arkmaker said, you don't have grip screws or even holes for them.  Its all held on by that pin holding the stock against the frame after the grooves i side lock up onto the little metal nubs on either side (of the frame).  In CMJ's picture, the brass screws are "extra"...probably to add rigidity.  The backpacker stock does have a tiny bit of lateral looseness.

Thank You guys for all this info!

Sometimes there's a tiny bit of casting flash in the frame hole for the pin, preventing it from dropping all the way done in the seated position. Very, and I do mean very carefully clean this out. If you get to aggressive your pin will fall all the way through the hole. Look at the pin, there is a ledge that matches up with the inside of the hole in the frame.

that pin also wears down the back of the stock and it gets sloppy.dont know how it takes to do that but thats what happened to my 1389 left a pin sized indent on the part of the stock it rests on
i would say a good tip would be to remove the stock after each use to save on the wear'n'tear

I use my 2280G as a pistol most of the time.  The pin hits the web of your hand if you install pistol grips.  Also the stock was too loose for me, so I removed the pin and use a regular stock.
