If you mean a pistol from the year 1750, MOST held 1 bullet, rarely, 2 bullets. This was still in the era of flintlock guns, loaded with loose powder and ball. No revolvers, no cartridge firearms. Most firearms were single shot- rarely, a two barreled gun that could fire one bullet from each barrel.
One
None. No such gun.
up to 20
6, IIRC
What model?
the semi-automatic 45 pistol holds seven rounds in the magazine and one in the chamber
The correct term is cartridge, not bullet- and the answer will depend on WHICH .40 caliber pistol.
9mm is a caliber, meaning a 9mm pistol is a pistol usually using the 9x19mm parabellum round. Therefore there is no exact number. A popular exampleof a 9mm pistol is the M9 handpistol, with a magazine size of 15 bullets, other pistols involves the CZ_75 holding approx 12 bullets to 20. depening on other calibers it holds. The pistol with most round are the ES Five Seven with a amzimum of about 30 bullets, while deringers (small one time use mini hand guns) can hold only 1 or 2 rounds.
It depends on the pistol make and model, and what it is chambered for. Most semi-autos nowadays hold at least 12 rounds. Most revolvers hold six.
Depends entirely on the pistol. I have a single shot muzzle loading pistol that 2 shots a minute would be good. A fully automatic machine pistol can fire more than 100 rounds per minute. You need to specify WHICH pistol, as there is no one answer.
Usually 6 but some models carried 5 and there even is a model that carried 9 shots.
It all depends on the model. Daisy made one that held 100 BB once.
