Needing some sun-sonic 22 ammo.
Any quantity appreciated.
Do they have to be shorts?
Academy often has the 'CCI Quiets' (750fps) and 'CCI Standard Velocity' (1080fps) - both subsonic; and Aguila Super Colibri (600fps).
All these have 22LR length case, and varying degree of 'quietness' (slower = quieter). but not in pistols - they will all be loud.
