Yes, you are going to be corrected. :P
There are a few 1911 style models chambered for .38 Super. May be some others style semi-auto's in .38 caliper.
Next time you run into someone like the old timer that stared at you, simply nod to them, smile,and say, "Good day to you, Sir/Madame" , and continue on. That's how it would have been done back in the days of the "Old Wild Wild West". Folks was very polite back then.
