Provide a detalied descrpition of ALL markings. Usually, the maker's name is on the slide or grips.
Yes- but not very common. There is an automatic pistol caliber known as the .38 Super, which does not interchange with the .38 Special revolver cartridge. There have been a small number of target pistols built to shoot .38 Special Wadcutter target ammo. And there is at least one auto pistol made in caliber .357 Magnum (revolver cartridge). However, revolver ammo is rimmed, and auto pistol ammo is rimless- there are usually feeding problems when an auto pistol is made for revolver ammo.
Not designed for full auto modification.
Get two pistols and put them together and it will make a double pistol! TADA!
For the same reason that most things are invented- to be a commercial success, and make money. The semi-auto pistol could be made smaller and lighter than a revolver, hold more ammunition, and reload quicker.
They do not make a nine shot pistol made by Iver Johnson. These pistols were available in the 1940s.
You take it to a trained gunsmith for evaluation and repair.
Not much information to work on, but Smith & Wesson made the Military & Police revolver for many years, and now make an auto pistol using that designation.
It would help if you gave the make, caliber, and condition of the pistol when you asked this question. Without that it all guess work.
There have been several semi auto .177 cal air pistols made. The most famous is the Walther PPk/s BB pistol. Not that many were made in .22 cal. But Daisy did make a model 622X back in 2004. It was a .22 and fired 6 shots. Hence the name 622. today there are two American air gun companies, not that well known, that make semi or full auto air guns. (More like machine guns) that fire .22 cal pellets. GMG and Air-ordnance. See the links below. I would not be surprised to see another .22 caliber semi pistol made due to the advances in air gun technology.
