S&W isn't currently making any 45ACP revolvers
but of my three (made between 2008-2016) all have chamber shoulders/ledges, plus the extra cylinder I purchased for Project 45WSM recently.
What year was your 22-4 made?
I read in a 2008 Handloader article that Brian Pearce said a decade or so earlier that S&W produced a batch of revolvers without chamber shoulder/ledges & that eliminated 45ACP rounds from being firing individually in them.
He reported in an earlier issue that after WWII they had a similar issue so while they've generally been okay apparently they've had some bumps in the road on this.
PS: I see the 22-4 was re-introduced in Oct-2005.
