Because the cylinder of a revolver (where the cartridges are held) must rotate freely, there is a slight gap between the front of the cylinder and the barrel. When a round is fired, the velocity of the bullet is determined by the amount of push it is given by the gunpowder in the cartridge as the bullet leaves the gun.
The Nagant M1895 revolver has a 7-shot cylinder, the Webley-Fosbery Automatic Revolver has an 8-shot cylinder in .38 ACP, the LeMat Revolver has a 9-shot cylinder, and the Smith & Wesson Model 617 has a 10-shot cylinder in .22 Long Rifle. As a rule, cylinders are not designed to be detached from the firearm (except for cleaning and maintenance).
The revolver has a 12 in (300 mm) barrel with no muzzle brake or ports. It is able to fire even the heaviest .500 S&W Magnum bullets weighing 725 gr (47.0 g). It has a clockwise cylinder rotation with a tight barrel-cylinder gap of less than 0.10 mm (0.0039 in). The interior and exterior are made of a hardened stainless steel.
The Nagant M1895 is a seven-shot, gas-seal revolver designed and produced by Belgian industrialist Léon Nagant for the Russian Empire.. The Nagant M1895 was chambered for a proprietary cartridge, 7.62×38mmR, and features a gas-seal system, in which the cylinder moves forward when the gun is cocked, to close the gap between the cylinder and the barrel, providing a boost to the muzzle velocity ...
At the end of the throat, however, things change. First, the throat in a revolver is at least as long as the maximum overall length of the cartridge; if otherwise the cylinder cannot revolve. The next step is the cylinder gap, the space between the cylinder and barrel.
The gun's entire upper assembly (barrel, cylinder and frame) are mounted on rails on the lower frame, which houses the trigger, hammer, and grip, and recoils 1/2 of an inch, or 12.7mm, on firing. The rearward motion of the upper assembly cocks the hammer, and the cylinder is rotated on the forward stroke. [ 2 ]

There is a modern revolver of Russian design, the OTs-38, [69] which uses ammunition that incorporates the silencing mechanism into the cartridge case, making the gap between cylinder and barrel irrelevant as far as the suppression issue is concerned. The OTs-38 does need an unusually close and precise fit between the cylinder and barrel due to ...
