Such a pistol would be an ideal weapon for shooting galleries and would popularize pistol practice, then pistol shooting would be a pleasure instead of a penance, when shooting has to be done indoors.
The automatic pistol inventors should experiment as follows:
The external lines should follow the Gastinne-Renette duelling pistol as nearly as possible.
The calibre and cartridge the same as it is (i. e., .44), the bullet being of lead, and spherical.
The magazine of a size to take only this cartridge, as otherwise, if a heavy charge cartridge were introduced by mistake and fired, it would smash and perhaps burst the pistol. An automatic pistol made for the light charge would have too weak a recoil spring to withstand a heavy charge.
The duelling pistol cartridge has the bullet seated far down it, and there is a lot of spare useless length in the cartridge.
In the automatic pistol I am advising to be made (the Winans model), the cartridge should be, though of .44 calibre, very short, the round bullet crimped in the end of it, like the .22 bulleted cap cartridges.
The cartridge being so short and the magazine made to fit, the usual high power cartridges would be too long to go into it by mistake.
The sights should be those of the duelling pistol.
I think such an automatic pistol would be much superior to any existing automatic pistol except for military purposes.
