I used to know some Russian, but it is not up to that. Is there anything in English?

basically an arctic warfare pistol that unlocks due to a pressure drop, but somehow is able to operate the slide, maximizing the energy potential of the powder.

but what the hell is the other trigger for?

I admit, I only skimmed the article.

This model from the discharge of unique in its performance and the assembly. Originally [PSH] was developed as side arms of the pilots of VVS. Developer of pistol - [V]. Shevchenko wanted to develop side arms for the armament of crew VVS (Air Force) and to replace with them army [PM]Pistolet Makarov, which by the way under the conditions of the extreme north and low temperatures was little effective for the self-defense from the wild beasts, since the low initial velocity of the departure of bullet at a reduced temperature of air leads to the fact that the 6-gram bullet released from Makarov cannot break even skin of polar wolf, to say nothing of what or fire contact with the enemy. However, when development was finished pistol was declared as weapon for the special subdivisions on the combating of terrorism and organized criminality. Apparently, reason lies in the disintegration of union, and model as side arms of the pilots of polar aviation would be not claimed. By the way it was declared on the participation in the tender for the rearmament of the FBI, but it did not fall into the number of participants. Pistol of Shevchenko [PSH]-45 of the caliber of 11,43 mm (.45) the development of Kiev design bureau the specials-technician OF [KBS]. Principle of the operation of the automation of pistol - recoil energy with the semi free lock. Cutoff of the bore of pistol by semi free lock - gas mechanical with the minimum flow rate of solid-reactant gases and the reliable wear and tear. Cutoff occurs with the peak of the pressure of solid-reactant gases at the initial moment of shot, and triggering - at the moment of a drop in the pressure, when bullet already leaves the bore, but residual pressure completely sufficiently for the reliable work of automation in the regime of blowback bolt. Design feature is the sufficiently uncommon bolt stop, which stops lock in the end rear position, showing pointer about the absence of cartridges; however, leaves in this case one ammunition of " the latter of [shansa]" , so that pointer sufficient to remove lock from the bolt stop and last cartridge it will be sent the remainder into the chamber. Weapon is so equipped with the indicator of the presence of cartridge in the chamber. One additional design feature is the lever of open action, with the snatching it is possible to mount firing pin spring by it, and descent is produced traditionally - by trigger.
Shevchenko pistol has eight modifications, developed on the basis of the new design solutions.

The top picture looks like someone crossed a P3AT, a 1911, and a 92FS, and then decided to give it another trigger to make sure no one missed its abomination-ness. That said, I'd love to take one to my local range

It's not Russian, it's Ukrainian, and here's the excerpt from my book Modern Combat pistols on that abortion of a gun:

The most intriguing small arms “producer” in Ukraine was the KB-ST (Design Bureau for Special Techniques). This highly controversial organization was established in 1993 and during the late nineties announced a series of a “revolutionary” small arms designs, such as sub-machine guns and sniper rifles of outstanding, if not unbelievable, characteristics. However, no foreign experts ever were able to test these “wonder weapons”, and by now it seems that KB-ST has folded and gone out of business. One of such wonder weapons widely advertised in Ukrainian literature as “unique” and “superior” was the Pistolet Shevchenko, or PSh in short. This overly complicated and strange-looking weapon was also an amalgam of previously known ideas, some of which were tried and rejected 50 or even 100 years ago. To start with, the PSh used a two-stage feed system, borrowed from the 1900-period Gabbet-Fairfax “Mars” pistol of British origin. This system, in which the cartridge is first pulled back from the magazine and placed on a lifter, then raised inline with the barrel and fed forward and into the chamber, was necessary because of the elongated barrel, which protruded back into the action. To further complicate the construction, its designer Shevchenko used a very rare gas-operated locking system first (and probably last) used in a WW2-era prototype Horn assault rifle from Germany. This system employs two small gas pistons that are forced sideways from the frame and into locking recesses in the slide. Another strange feature was a hand-cocking device, probably taken from HK P7 pistol, but in a twist – instead of full-hand cocking lever PSh employed some form of a second trigger, located below the “primary” trigger and used to cock the striker when pressed by one middle finger. If you still not have enough of this design, it also had a ribbed, aluminium jacket on the barrel, and a very special sort of slide stop, that locked slide open once there was ONE cartridge left in the gun. The claimed purpose of this arrangement was to allow shooter to make its “deliberate last shot” – in its own head, probably. Not surprisingly, this weapon, “available” in 9x18 PM, 9x19 and .45 ACP, never went past magazine pages, and probably, a handful of prototypes. Nevertheless, the author decided to include it, if just for the amusement of the readers.
