Yes, HeroHog, I know, having read it hundreds of times in writings by people who specialize in myths. Actually the Super Star and Llama Extra will handle the .38 Super with no problems if they are set up for the semi-rimmed round. (Even the .38 Super +P runs about the same pressure as the standard 9mmP, 35,000 psi.)
The same writers almost always tell us that the Astra 400 will fire the 9mm Largo, .38 ACP, 9mm P, .380 ACP, 9mm Steyr, etc., etc. One writer even said it will fire the .357 Magnum and .38 Special! Now that would be real versatility.
