A silenced 22 HG can be 9" OAL, if you know

how to go at it, and the package will group 2" or better at 25 yds, 2 handed unsupported. What you do is shorten the barrel of a Browning buckmark to 3", and reduce the OD of the front 1.5" to 3/8". you thread the rear 1/2" of that 2" of exposed barrel 1/2-20, and have baffling telescoped back around the barrel, The gun at that point is 7" long. The tube with the baffling in it has to be vented around its rear 1.5", and a "sleeve tube' is welded around the internal tube, with a washer welded between the tubes at each end. Inside of this "sleeve area", the internal tube is wrapped with copper screen wire. The hottest, highest pressure gases are vented into this area, have to pass over the screen, bounce off of the front washer, pass over the screen again, and then reenter the rear of the silencer, after the other gases have exited a bit.

Underneath the sleeve tube, you have a "trough" or "underchaamber, making the can look a bit like an o/u double shotgun. This area is welded gas tight, and contains vertically oriented rectangles of copper screenwire. The rear 1.5" of the sleeve tube, at its bottom, is vented into this "trough". When used wet, and the slide is locked shut, this assembly makes normal 22lr high speeds sound like a BB gun, and if you let it cycle normally, it makes about as much noise as a soft handclap. Since there's only 2" of baffling in front of the barrel's muzzle, the sleeve area and the trough have to do a lot of the work.

9" OAL is the same size of gun as a Beretta M9 or a 4" k frame 357, so it can definitely be ccw'd, (and drawn swiftly).

Another brilliant example of copy and paste wisdom.

Thanks for detailing your commitment of a felony. If you leave the door of your mom's basement cracked open, ATF may not breech it.
