Oct 4 '15 at 2:14 comment added Llamageddon Yes, I'm aware of muzzle brakes, was primarily wondering if some leftover pressure/gas could be used to compensate for hand tremble when squeezing the trigger(even if it's not really so significant), or whatever else. A bore evacuator could be useful for being able to chamber the next round faster, especially with caseless(and as such, not impossible to ignite with some hot gasses) ammo, or even just "more safely". Most of my thinkings is just theoretical considerations as a hobby :P

Oct 1 '15 at 0:58 comment added Carlton There's a third type of gun that you may find interesting: the recoilless rifle. It is essentially a gun with an open breech, so that some of the propellant gas discharges rearward during firing and counters the recoil generated by the bullet. This may be tough to implement on a handgun though because the gas would hit the shooter in the face. They're typically shoulder- or vehicle-launched so the exhaust gas can be directed in a safe direction. You could look into muzzle brakes too; they don't store gas, but direct it in some other direction than straight ahead to reduce recoil.
Sep 30 '15 at 23:55 comment added Llamageddon Found some fascinating info about a handgun that uses cartridge-contained captive pistons, brilliant. What I haven't found a whole lot of resources about are bore evacuators - not a single use case outside cannons and tanks, also no easily accessible efficiency info. Intuition says that they should be able to trap up to half the gasses, probably less, in addition to the function of preventing backwards flow(in case of tanks). Should probably dig a bit deeper, but guess I'll ask anyway - can you imagine using them for recoil control in a handgun?
Sep 29 '15 at 19:25 comment added Llamageddon Thank you for the excellent answer. I'll probably accept it, but as a personal rule I always wait a day or two. :)
