Our initial research data covered the relationship between barrel length and velocity for some 13 common handgun calibers/cartridges.
1 Οκτ 2013 · The real determining factor in barrel length vs: velocity is total volume of the chamber and barrel. The lower the volume in proportion to the chambering, the more dramatic the velocity loss is by shortening the barrel.
Switching to an early 61/2" Flat-top Blackhawk gave a muzzle velocity of 1,270 fps that was only 5 fps faster than the 50th Anniversary model with nearly 2" less barrel length. An Old Model with a 71/2" barrel registered only 5 fps faster than an Old Model with a 45/8" barrel.
