What do they cost? I am looking at purchasing a P22 and don't know if I am better off with a 5 in bbl to start with or just the 3.4 in. I intend to add a suppressor to the pistol and will probably shoot it most with the suppressor installed. Does the extra barrel add much to desireablity for later sale??? I have found a new in box 3.4 in for $250 and a like new in box 5 in for $265 shipped..... not much difference in pricing...someone help a newbie.
