Hello all, long time listener, first time caller. I have been in the market for a new shotgun for some time now. I have finally decided on the Beretta 1301 Comp. My predicament is, that I cannot decide on which barrel length. I'm primarily going to use this shotgun for fun, ie.., clays, target shooting, and possibly three gun when in my area. With all that in mind, I'm leaning towards the 21", but any and all advice is greatly appreciated. Thanks!
