I'm considering picking up at a G-20 for which I will mostly use it for a woodsgun. As such, I plan on shooting either Double Tap or maybe Buffalo Bore. With this in mind, should I get an after market barrel like Lone Wolf? I've read on the internet (and we all know what that can mean) that (1) the barrels are a little more accurate and (2) they are safer with the fully supported chamber. Are these legitimate reasons/issues or simply internet BS? Any other suggestion would be welcome as well. THANKS!!!
