I have a bunch of SS mags for my 38 Sup, but I bought them all without base plates. Now I want base plates. Am I better off buying more mags with base plates already attached or should I just add base plates to the mags I already have, and if so what are peoples opinions on which ones are best. I don't know if there are pros and cons to the add on plates versus factory installed. .... I know, newb question.....
