My only Taurus revolver is a model 455 . It is a 5 shot , stainless steel , small framed , fixed sighted revolvcer in 45 acp. The 2 inch barrel is factory ported . It carries a lot of firepower in a small , shootable , package. Think J framed S&W in 45 acp.
I own 4 45 acp semi auto pistols, the Taurus is the most accurate of all ...it's spooky the tiny groups it shoots , I would buy a 3 or 4 inch barreled one with adjustable sights in a heartbeat. Tight tolerances , chambers , throats , barrel gap and bore ....all this adds up to the good accuracy. I have no bad things to say . Owned since 2004 and shot often .
I do not own a Charter arms so can't speak of those.
