Description
PT-52. Pistol-Tulya, Model 1952.Overview:
With the ending of the Patriotic war, and the looming threat of a future war with the West, Strania continued to innovate and reform it's military in the post-war period. With advancments like the adoption of the MBT-55, and ST-51. The PT-52 represents the modernization of the pistol.
Following a similar trend to the service rifle, the PT-52 uses a lower-powered intermediate 7.8x24mm cartridge compared to "full" powered 10x26mm. Though for the sake of modularity, and power, the PT-52 was designed with the requirement to be adjusted to 10x26mm with the replacement of the slide and barrel.
Design:
The PT is a single-action pistol with an external hammer and de-cock/safety lever on the left rear side of the reciever. A magazine catch is located at the heel of the grip. Early models had issues with firing block pin springs but this was rectified in the PM.
The PT used an unusual form of short-recoil system in which two vertical rollers are used to lock the barrel and slide together via a cam block. Allowing for a strong lockup that allows the loading of higher-pressure ammunition. Allowing for the PT, with a suitable barrel, to fire the powerful 10x26mm cartridge. As well as overpressure 7.8x24mm ammunition.
Due to the roller-delayed system and fixed barrel, the PT is a relatively smooth firing pistol for a blowback system, and more accurate when compared to most tilting, rotating, and articulating barrel handguns.
However, early models had poor heat-treatment of these rollers, leading to damage and unreliability. With few PT pistols being chambered in 10x26mm, or with high-pressure ammunition developed alongside the PT. This issue would not be fully recitfied until as late as 1974.
The 7.8 cartridge was chosen specifically for power and high velocity, while recoiling less than the "Harsh" 10x26mm cartridge.
The 7.8x24mm cartridge can out-preform 9x20mm in range and velocity. But is roughly matched in terms of energy delivered into the target.
While 10x26mm delivers both a higher-grain projectile further than 7.8, this comes at the cost of high recoil and a unweildy and heavy frame. Leading to a bulkier pistol and higher costs. As most pistols in military envionrments are used for policing actions rather than outright combat, this becomes a detriment.
The PT offers a more compact, lighter package than the Koltarev, while also being simpler to produce and easier to control and train.

Military Remarks:
"I miss my Koltarev... Sure, it kicked like hell and hurt your wrist. But that was the fun of it man!"
"They say seven-eight kicks less than ten-mil but I call bullshit. Still flicks your hand like you touched Grandma's cookie jar."
"I like it. Smooth, accurate, reliable. I haven't had any troubles with it yet. Also a heck of a lot smaller than the Koltarev was. That thing always tried to pull my belt down."
"Those things? I never liked them myself. Those rollers never worked, gimmicky crap. But give me a ten-milimeter? Oh I'll do some fantastic works with that."
"If you get one of those supressed ones? With the subsonic seven-eight? Man you can shoot it all day brother! Smoothest cycle I've ever seen from a gun."
"I heard a story once from one of my buddies. He was entering a house and got his rifle shot, pulled out his ten-mil and shot a few rounds into a guy, but opfor had a plate carrier so it didn't do shit, he got shot in the leg because of it. Personally? I'd rather have my seven-eight with some armor piercing."
"The seven-eight? I like it. Light, reliable, compact, what's not to like?"
"I like them but, damn they wear out fast man. Only a few hundred rounds through them and they start to throw bullets way off course. It's just not big enough for that kind of power."
