I think there must be more to the snubbies low recoil and low G performance than just using a low pressure round. Of course, the fact that snubbies presumably have such a low MV (at least in canon) means that the round is almost certain to be subsonic. Coupled with the low recoil, if you silenced a combat snub or Snub SMG it would be perfect for clandestine operations (at least short ranged ones...).
Well, it would possibly make the weapon less painful to fire, but it wouldn't really affect the degree to which recoil knocked you off balance. Of course, dropping the muzzle velocity down to 75 m/s like an M203 would certainly cut down on recoil.
A small caliber high velocity pistol is probably the best sidearm for zero G.
Yes, conventional propellants are generally given a maximum theoretical velocity of about 6000 fps. it's a limit imposed by gas 'drag', and the reason high velocity test guns use helium.
You probably notice that there aren't many conventional small arms that exceed 4000 fps. The problem is that current propellants themselves only expand at about 4000 fps.The practical limit is generally given as about 4800 fps.
ETC guns can overcome this because they are using plasma stimulated working fluid, and not depending on propellants deflagrating and generating byproduct gasses.
Only indirectly. I ran the numbers based on the canon velocity of the projectile. A longer barrel would probably increase recoil energy - assuming velocity is increased. This is typically offset because a longer barrel also increases the mass of the weapon.
You can run the numbers here:

Well, if your only objective is low recoil, yes.
Incidentally, recoil energy, while relevant to the controllability of a weapon, probably doesn't have much to do with the degree to which the weapon will throw you around in zero G, which is more a function of total momentum transfer. However, I have my doubts that recoil in zero G is really that much more of a problem than it is on the ground, firing a gun while floating in zero G isn't going to be terribly easy regardless of the weapon, and if you're holding on to something, breaking your grip isn't really easier than knocking someone down on the surface of a planet.
Well, given Traveller equipment, your MMU probably has effectively unlimited delta-V, being a reactionless thruster probably capable of somewhere on the order of 100N indefinately.
Even if you don't have Traveller equipment, your MMU is likely to have on the order of 1000 Ns total delta-V. A 5.56 assault rifle or a 9mm pistol produces a total impulse of about 4 newton-seconds, so dumping 30 round clip will set an 80 kg man drifting backwards at 1.5 m/s, which your MMU should be able to compensate for in seconds.

re: snub pistol:
lateral venting of exhaust gases would compensate for recoil wouldn't it?
grrr..... description states revolver, picture is autoloader.........
i hate that

At TL12, recoil-reduction IMTU is sufficiently advanced to look like magic to my players and I.
