Offering a Revolver is almost like offering a Sword, if better. Also, why the M10 designation? Do we need letter/number designations, what are they used for?
I'll give a design a shot I guess, hopefully a good one.
Behrens Semi-Automatic 'Valturia' Pistol
As Behrens Jr. himself said, we pride ourselves on craftsmanship. We've made a few Mauser C96 pistols under license, but we can do better. The parts are milled from scratch by our company, the barrel carefully grooved to give the bullets a spin, and the seven-ammo cartridge placed in the handle for reloading. A simple press on a switch near the top will cause the ammo cartridge to unlock, dropping it to allow a new cartridge to load into place. The handle designed to be ergonomic, and the outer casing of the gun sleek and slim to not catch when concealed while remaining stylish.
Recoil Operation is used, and our handmade milling allows innovation in the form of a slide over the 90 mm barrel. This means that it does not stick out like some designs, meaning concealing it is much easier. Our craftsmanship renders our products quite reliable and hardy, as the products we make often last a long time. So long as you keep them oiled and cleaned, they will serve you well. By industry standards, the Behrens Valturia Pistol falls under the beginning of the Compact classification and uses the 8mm Behrens cartridge. Each comes etched with a signature from the finishing craftsman and numbers telling the year it was made in as well if it's the 1st or the 1000th that craftsman has done, so not only do you know it's Behrens Quality, but the government can track them.
Name in honor of country, and mostly aimed at the Royal Police. I think having one of the first sets produced might also be a good motivator for collectors in the future.
Also, can someone do a logo of a clock?
A pocket revolver is concealable, but it doesn't fit well in your hand at all. Compact means it does with or without a cartridge, which will help when using it.
90 mm comes to a tiny bit above 3.54 inches. It's right over the Sub-compact limit, but will make operation easier when reloading.
