I'm having some trouble trying to understand the difference in Blowback and Locked Breach automatics.
Locked Breach seems to have a barrel that is seperate from the frame. The breach is on the slide which interlocks with the barrel before being ready to fire. However, the breach is only sealed by the cartridge so I'm not sure I understand the term locked-breach. I guess in a way it is locked with the barrel but it certainly isn't sealed except by the cartridge.
Blowbacks seem to have a fixed barrel. And if I understand correctly the breach/bolt is not interlocked in any way. It's like a solid tube pushing the bullet into the barrel and then firing it, with the bolt being kinda free wheeling. Again, the cartridge seals the chamber. (I don't have one of these so I can't look and see.)
I know I got most of that wrong somehow. Anyone got a better explanation. And why would a Blowback have a worse recoil? It seams to me that which ever you use it's still just going to be the force of the bullet pushing back on the gun. All this came about as I'm looking at the difference in the little .380 and 9mm pistols. Most of the .380's seem to indicate the blowback mechanism and the 9mm has locked-breach. Why not have a 9mm blowback? Isn't the .45 ACP Tommy Gun a blowback? I know people say the locked-breach is better...I'm just trying to understand why?
