For manual operation, given the low-gravity circumstances, a lever-action shotgun like the Winchester 1887 (updated of course) might prove the least disruptive.
A purpose-built weapon, like the accelerator discribed in book4, would have to have a very low moving mass in the action. Given the low-recoil, low-energy nature of the round a light bolt isn't a problem containg the pressure. However, a light bolt and the weak buffer/spring that it rides on will have a great deal of trouble stripping the rounds from a comventional magazine. Balancing this system could very well end up producing a magazine very similar to the one used in Nerf guns; self-lubing polymer with a very light spring. Given the weight of an accelerator round the light spring would work in 0-G but have trouble lifting 15 rounds in a 1-G gravity field. The only other solution I can come up with is a powered magazine that moves rounds upward whenever the bolt travels rearward. While not mentioned in the canonical description I wouldn't consider this beyond the description as magazines in Traveller seem to be disposable; i.e., ammo is sold by the magazine-full.
