His conversion isn't a blowback gun
, but rather a direct gas impingement design, and he kept the standard bolt/carrier configuration.
What do you do if you want neither the moving barrel, links and lugs of a conventional locking system, nor the violent kick of a straight blowback gun
in 9mm Luger?
Although a gas block is not needed on this blowback gun
, I wanted one for cosmetic reasons.
Since the 1911-22 is a blowback gun
, the barrel does not move in recoil, but neither is it permanently mounted to the frame--in fact, the pistol field-strips just like any other M1911, down to the barrel bushing.
With some blowback guns
this would be a big deal but, frankly, it was no trouble to shoot from either side with the brass ejecting in front of your face.
tend to spray a lot of gas out of the ejection port.
