I have been shooting .38 super for over 35years, in competition and for fun....
and have never had an issue with single stack or double stack guns using the .38 super round..... I have never felt the need to use .38 super comp brass, and all of my .38 super guns shoot JHP rounds without issues....
If a single stack .38 super is having issues, more often than not, the mag seats too low in the frame, and strikes the feed ramp too low causing issues. If a person can seat a .38 super mag in their gun, and there is a lot of vertical play once the mag is seated, an Evolution Gun Works 1911 high mag catch will raise the mag up to .020" in the frame, which helps to eliminate bullet nose dives.
In addition, if the feed lips of any .38 super mag are too wide, and the top round sits too high above the feed lips, this may be an issue that prevents reliable feeding.....
