Wow. Back when I first got into reading about pistols extensively, 40 years ago, 38 Super had a reputation for poor accuracy. Not long after that, it became popular in certain types of shooting competition (IPSC? Does that still exist?), people put a lot of work into it, and reported accuracy went way up. I vaguely recall some writers speculating that older guns relied on the semi-rim for headspace, whereas newer ones headspaced on the case mouth, which was apparently better, but I have no idea if that made a real difference or not.
This does not matter at all now, of course, unless you get your hands on a gun more than 35 years or so old.
BTW, I have occasionally thought that a compact, DA, gate-loading rod-ejector gun in either 45 ACP (5-shot) or 38 Super (6-shot) might have made more sense than the Charter Arms Bulldog in 44 Special, but that is A) probably not true, and B) water long under the bridge. Nowadays you would make it in 9x23 or 10mm, but who wants a gate-loaded rod-ejector pocket gun? Too heavy, too bulky, and not enough shots.
PS - cfullgraf, I am sorry I did not read your post until too late. I could have saved myself the trouble of writing mine.
Nevertheless, I am glad to see I am not talking through my hat.
Also, I agree with 460Shooter about what the writer brutus51 quotes meant. At least that's how I would interpret it, too.
