U.S. Pistol Company DID make a 7 shot smoothbore revolver, but it was not a starter pistol (blank gun). It fired live .22 ammunition.
Do not confuse w/ US Revolver Co. (1910-1935) which was a trade name of Iver Johnson's.
US Pistol Co was an entirely different firm and was owned by Otis A. Smith. The company was out of the gun business by 1899 (switching to tools) The guns were designed for low pressure Black Powder cartridges only.
It will usually be marked somewhere on the barrel.
It should be marked on the barrel.
Depends on the caliber, barrel length, projectile weight.
What is the caliber, barrel length, finish, grip material, markings on barrel?
Caliber is the size of the barrel's inside diameter, in fractions of an inch. A .25 caliber pistol fires a bullet that is about 0.25 inches across. Pistol can range from very small (about 10 caliber) up to very large (75 caliber) and there are hundreds of different cartridge sizes in between.
The COP company (now out of business) made a 4 shot .357 magnum, but cannot recall a 4 shot 44.
4 inches including chamber.
ABOUT $150, depending on condition.
Need to know caliber, barrel length and whether it is a revolver or semi-auto pistol in order to answer.
Turn of the century
suggest you check writting on barrel. it should indicate caliber..............
One can make a pistol much larger than it needs to be, maybe even having an extra-long barrel would make a pistol larger, technically. I'll assume you mean the barrel diameter. Although it would seem that a .380 and .38 would have the same barrel diameter, namely, 38/100th of an inch, that is not usually very accurate. The .380 ACP has an actual barrel diameter of about .35 caliber, or 35/100th of an inch. The .38 Special has a barrel diameter of .357 caliber, or 35.7/100th of an inch. So the .38 Special has an ever so slightly larger diameter.
