The only unsafe CVA's are the 1995 and 1996 inlines. No CVA Sidelock has ever had a recall or safety issue. You can tell this by looking at the last two digits in the serial # on an inline.
What you are reading about CVA being unsafe, is coming from a Savage Salesman trying to use scare tactic to bring business over to his end.
The CVA Plainsman is one heck of a shooter, i had a .50cal flintlock and that baby loved 70gr 3f goex and a 405gr powerbelt. Also did really well with patched round balls.
