I'll smack myself when you tell me,  but what's that second unthreaded rear hole for on the 22xx/17xx/prod grip frame?

It's for a pin to make a quick-detachable stock.  I have only seen it used on the 1389 backpacker.  I did not care for it because the pin hit my hand and the stock was too loose.    :)

I figured as much haha.. I'll find a nifty use for it,  tho my current 2250 build does need a stock of some kind.. How stable was the 1389 stock for you?

Oh damn.. Nevermind.  Stock loose,  gotcha.  Wonder if any of the craftier Folk here found a way to tighten it up?

The way I've dealt with slop in the stock is to drill a hole through the bottom of the plastic up into the trigger frame casting, then tap the hole for a #6-32 machine screw.

ive found that #60 orings from lowes placed on the tiny pins that guide the stock onto the frame make it rock solid

The stock is not super loose, and would probably be all right for actual use in a back pack, but the main problem I had with it was that the protruding pin irritates the web of my hand. The o ring fix looks good.  :)

The pin has been an irritant on all my pumpers.  Doesn't bother all folks though.

I use some blue painters masking tape on the bottom of the grip frame and a bit on the back  of the frame.  Usually  doesn't take much to get rid of the "wiggle".

sure thing......


i circled the pins on each side of the grip frame that you add the orings to,
they slide into slots on the shoulder stock as you install it.

i use a total of 4 #60 orings,oil or grease them lightly for best results.

and as you slide the stock on (SLOWLY) squeeze the first set of orings tight to the stock with your thumb and index finger,
until they are fully inside the stock,
repeat for the second set, then install the grip screws.

makes for a rock solid stock.

Now THAT is awesome - I wouldn't have ever thought of that. Well done, thank you for sharing.

In the past I used a piece of leather/felt to secure the stock but I like your tip much better. Thanks once again.  :-*

Great idea i used electrical tape cut to shape of the grip frame to thicken it up and help grips from sliding have had good success but will  definitely  try this.
