Get a storm lake conversion barrel for you G23 to 9mm. Then get a YHM Cobra M2 9mm can and shoot it on 9mm and 22LR. 40 cans kinda suck. I decided to go with a Trident 9 first and would do it again in a heartbeat. I love suppressed subsonic 9mm. It isn't Hollywood quiet like .22 can be, but it is a much funner quiet to make IMO.
