I might add here that Chic Gaylord's book is the only book I have seen in the popular press, though now hard to find, that showed actual gunshot wounds. A dose of reality can be a little hard to take when you are speaking of shooting people, even though the wounds are cleaned up.
As far as the 38/44 and 200 grain bullets go, gunwriters of that period tended to recommend revolvers with at least a four-inch barrel and for more than one reason, the relevent one here being the velocity issue. Most of them also were inconsistent at times, just like I am, and generally illustrated their books and articles with 2-in barrel revolvers, including .22's, as well as others. Even Elmer Keith said there was no need for a holster for the j-frame because it was strictly a pocket gun. Yet in a very good article in Guns magazine from around 1960, he shows his own j-frame, complete with holster. Keith himself preferred a holstered N frame for concealed carry.
The British, when they went to the .38 revolver after WWI, used initially a 200 grain lead bullet, later changed to jacketed, in the .38 S&W chambering of the Webley and Enfield revolvers. They did not change over to 9mm until well after WWII.
