Unlike a lot of .380s, the Spectrum is not a straight blowback gun
. It features a tilting barrel that helps absorb some of the recoil forces.
Caption: As a straight blowback gun
, the Accu-Tek AT-380 II is a good bit bulkier and I heavier than more advanced short-recoil designs, like this customized Smith and Wesson Bodyguard .380.
The entire time the bolt carrier was slowly slapping back and forth like, well, a blowback gun
. I suppose this isn't surprising considering the PTR 32 utilizes the classic roller-locked delayed blowback system.
What is the difference between a blowback gun
and one that is not.
The 389TS is a simple, straight blowback gun
with a 16.5-inch barrel.
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?
No, a 9mm does not inherently have more oomph than a .223, but a 9mm AR is a straight blowback gun
, with the heavier bolt/carrier heading back toward your shoulder as soon as that hammer falls.
This pistol has the standard Glock barrel lockup, and it is not a straight blowback gun
, as are many ,380s.
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.
The barrel is fixed in place in blowback guns
, or at least it's not locked with the slide.
