I've got a 9422XTR that is probably my favorite 22 rifle. Everytime I shoot it I ask myself why didn't you buy one of these a long time ago. The problem with mine is the magazine tube falls out of the gun when no ammo is in it. Is there some easy way to put a little friction on it so I don't lose it.

My 9422 did this also, I simply bent the little tang the pin in the tube hooks under to provide a little friction on the tube.
My Henry has an "O"ring on the tube that squishes under the tube knob and the outer tube, I tried this on the Winchester but you would need a very skinny cross section oring for the Winchester.
