Oh yeah I have primary calibers but would get too bored without some variety. .38spl is what my Grandad carried. I will always have a couple of them around. As for the market, there are some great guns floating around out there in .38spl. Good deals are not hard to come by either.
This is why I like my .357 pistols. Have two options, .38 or .357.
Alert! Alert! Found some 223 if anyone needs it!
