The quality of the barrel is also very important. For example, a Manhurin 4" barrel is much better than a 6" Ruger one (S&W are pretty good too). However, a longer barrel, makes a gun easier to use: it is more stable and has a longer line of sight. A longer barrel makes a better use of the enegry delivered by the cartridge: a quicker bullet will be more stable (and then more accurate) than a slower one. Any comments or other idea?

I have a Dan Wesson .357 with a 4" bbl and it is unquestionably the MOST
accurate out-of-the-box handgun I've ever seen. I believe the reason for this
(other than the high quality of manyfacture) is the the bbl is fixed at BOTH
ends, and is held under tension between the frame and the end of the bbl shroud.My theory is that reduces the amount of whipping back and forth the bbl does as
the bullet is on its way out the bbl.
Just my $.02 worth, Jay
