New to CCW and guns a bit. Trying to decide on barrel length for carry

So I’ve done plenty of looking and have decide upon a Shield Plus Performance with fiber optic sights. I’d shot some previous shields so I know for me that I shoot better with this line of guns. I love the new trigger and the sights are great. The only thing I don’t know about is whether to carry with a 4” or 3.1” barrel. Suggestions y’all might have? via /r/CCW https://ift.tt/31iS2Z3
