I'm thinking of buying beavertails and polymer magwells for my G19 and G17. The G19 is carry...not sure if the magwell adds any appreciable width. The main attraction is faster/surer grip (both) and the beveled edge for faster magazine change (magwell). I'm thinking these are pretty small changes and it's not like the guns don't work great without 'em...but you know...it's fun to Glock out sometimes... Thoughts?
