The sword handles/gun barrels have locking slides (muzzle end is slightly smaller). The flip-back is on a hinge (wouldn't be noticeable if made IRL). The connection is through Gravity Dust integrated into the composition (same reason they stay closed in pistol form). The pistols are based on FN Five-seveNs.
