The Pin Gun Class evolved out of Jim Clark's original barrel weight for 1911.45's, the
expansion chamber compensators that followed and--to a lesser extent--heavy custom barrels on revolvers.
Optimal partition layout of
expansion chamber m uffler with offset inlet/outlet, International Journal of Automotive Technology 16(5):885- 893.
That's where the attachment point is in the middle of the tube, and the
expansion chamber goes back over the barrel.
Using a 6.75" match-grade barrel and ports that are designed to support the host suppressor, the 12" suppressor features a large

The configuration of the helicoid and the central tube in a simple
expansion chamber which is the subject of this investigation is a modified version of the Herschel-Quincke tube [7].
Each top port has an
expansion chamber. The
expansion chamber is wider than the passageway for the bullet.
It is worth noting that this mode of cloud formation, allowing steady cloud microphysical conditions for times much greater than typically available in an
expansion chamber, opens up a number of experimental possibilities.
The only hints of chrome left are on the
expansion chamber fins, rim linings, and the rear brake and shift shafts.
