John Moses Browning’s gun fact dump

1978. Accuracy International is founded. Three men, Malcolm Cooper, Dave Walls, and Dave Caig, each bringing their own specialty to the table. Operating out of Walls’ garage in Portsmouth. Cooper, an Olympic gold medalist. Walls, a precision machinist and gunsmith. Caig, an engineer and toolmaker. Rather than the traditional manner of a wood stock, they elected to make the full receiver and screw it into green plastic stock halves, giving them a unique advantage in modularity and ergonomics. 

1982. Britain is in the Falklands War. The Brits are using a modernized Lee Enfield converted to 7.62x51 NATO (.308 Winchester). The prolonged water exposure and cold in the Falklands exposed major issues in the design of their rifle. The wood stocks trapped moisture causing warping and swelling, pressing against the free-float barrels, heavily affecting accuracy. The MoD initiated the Infantry Sniping Trials in the early 80’s to find a replacement. Out of a reported 17 manufacturers competing, Including Heckler and Kock, SIG Sauer and Remington (jesus shit), it was narrowed down to Accuracy International and Paker-Hale’s M85. The AI demonstrated higher durability and ease of maintenance. The Accuracy International PM achieved 0.5 MOA ten shot groups at 100 yards with 168 grain match ammunition, and maintained zero regardless of barrel temperature or environmental factors.

When Accuracy International submitted their rifle, they really had no intention of winning. They were basically pushed into it. The only profit they were really expecting was professional evaluation on their design and constructive feedback. However, their rifle was too good, and the Bri’ish gave them a contract for over 1000 rifles. This would usually be a major success. However, three guys in a garage didn’t exactly possess the capability to produce 1000 rifles in this timespan. Before the contract was to go through, the MoD required an audit to ensure industrial capacity, workforce and manufacturing facilities required for the order. This is where the funny story begins. The three men decided to stage the inspection. They rented out a workshop and transferred all their tooling, machines and rifles to there. Different parts of rifles were placed all around in different workbenches to sell the illusion of an active assembly line. When MoD inspectors arrived, they found the facility empty. When asked, the three men simply responded that all the employees were on their regularly scheduled lunch break. Nothing out of the ordinary here. Usually this would be hard to believe, the entire workforce going out for lunch at the exact same time, but they were reassured by the professional setup of the place. They then all went out to lunch to finalize everything, where the inspectors famously remarked that the whole inspection thing was really just a formality to ensure they weren’t just three blokes in a shed, completely unaware that these three men were, in fact, three blokes in a shed. 

However, this carefully sculpted illusion couldn’t be held up indefinitely. Once MoD realized that they were really three blokes in a shed, they mandated that they sub-contract to fulfill their obligation, with final assembly and quality control by Accuracy International. This emergency sub-contracting was a nightmare, as the sub-contractors struggled with the tight tolerances the three blokes had so passionately and precisely designed. Some dumbasses decided to cut corners and make un-authorized changes to make time, resulting in major quality failures. Realizing that these shitasses threatened to destroy the rifle’s reputation, Accuracy International cut ties. Accuracy International rapidly developed from three blokes in a shed to the actual professional manufacturer they lied about being prior. 

Now on the sterling toughness of the rifle, I am far too tired as of writing this to properly speak on this, so I encourage whoever is interested to look into this topic themselves. However I will talk on the AWP version. In the late 80’s the Swedish Defence Materiel Administration wanted a rifle optimized for sub-zero conditions. Accuracy International redesigned their platform, resulting in the Arctic Warfare rifle family. The Swedish demanded operational functionality in temperatures as low as -40. Normal bolt-actions would fail under these conditions, as moisture freezes inside the receiver, welding the bolt shut or preventing the firing pin from striking the primer. Consult Garand Thumb’s freezing pistol, rifles and shotgun tests. To address these functional concerns, AI cut long channels into the bolt that scraped away ice, packed snow, whatever during cycling. Controls were optimized for thick, unwieldy gloved hands, such as the thumbhole in the stock, bold knob, trigger guard and magazine release lever. A quick change barrel was designed to allow a quick field change within two minutes. Gas relief ports and improved striker seals were included to prevent water ingress and safely direct gasses away from the shooter in case of a catastrophic casing failure. The Swedish adopted the platform in 1991 as the Prickskyttegevär 90. Recognizing the superior resilience of this improved design, the British replaced their original Accuracy International rifle from earlier, designated as the L96A1, with the new rifle, designated the L118A1. Truly a majestic naming scheme. Theres more but im tired man

The .357 SIG cartridge 

.357 SIG was invented in 1994 by essentially taking a .40 Smith and Wesson casing and bottlenecking it down to accept a 9mm bullet. The goal was to replicate the power of a .357 Magnum in a semi-automatic. 



The .357 SIG offers high velocity for a pistol, usually 1400-1500 fps at a 124 grain projectile.



The bottlenecking also promotes better chambering.



And since it uses a .40 S&W casing, .357 SIG and .40 S&W are compatible. You can shoot both in the same gun with little more than a barrel change. Both work in the same magazine.



However, it is near dead now, as advancements in projectile technology have made 9mm the dominant cartridge. 9mm has more capacity, cheaper ammunition, less recoil, more availability, and is less damaging to the gun compared to .40 S&W and .357 SIG.

.380 ACP, 9x18 Makarov and 9mm (9x19). If you look at the dimensions, you’d think 9x18 Makarov is right in between .380, being a 9x17, and 9x19. But 9x18 Makarov is actually closer to .380 in terms of power. The SAAMI pressure spec for .380 is 21,500 PSI, around 23-24,000 PSI for 9x18 Makarov, and 35,000 PSI 9x19mm. The first number is the actual diameter of the bullet. The second number, 17, 18, 19, is the length of the bullet. 9x18mm Makarov is actually closer to 9.2-3mm, being a .365 inch diameter bullet. .380 ACP and 9x19mm are .355. 9x18 Makarov is also closer to .380 in terms of overall cartridge footprint, bullet weight, velocity and firearm size.

Uh- oh shit uh yeah I’ve kinda run out of gun facts off the top of my head so uh… I’ve been thinking a lot about the SIG Sauer P250… it’s the gun the P320 ballsack destroyer™️ is based off. The P250 is a Double Action Only, meaning your pull of the trigger pulls the hammer back, cocking it, then releases it, resulting in a long, heavy, cumbersome, trigger feel. The hammer is tall, which explains the odd, tall, rectangular backplate on the P320. The P320 was, and is, just a P250 converted to striker fire, which may explain its various issues, along with other factors. The P320 grip modules are actually interchangeable with the P250, since the P250 has the same FCU design, although I think the metal AXG modules don’t work for the P250. Maybe I’ve been thinking about the P250 a lot because it’s the sidearm the MLO carry in A New America in Ready or Not’s Boiling Point expansion, and well I’ve had plenty of time to think about it there because it’s been like 30 fucking attempts. I got close on my first attempt, but accidentally shot the triggerman and well accidentally committed domestic terrorism. Then I went into quick play as to not constantly feed squad teammates into a fucking meat grinder, and I decided well, while I’m here, might as well go into hard mode. Can’t be that hard, I got to the final room on standard! I was wrong. So very wrong. 30 attempts later, back in commander mode on STANDARD difficulty because I do not partake in massochism, and uh in my latest attempt, I got to the final room. I learned from my mistakes! I cleared all the floors before activating the signal, which of course starts the 2-3 rush upstairs to disarm the triggerman, and I held my teammates outside the final room because the AI REALLY loves to shoot the guy, that if you shoot, you commit domestic terrorism because he has a deadman’s switch. So I get to the door, open it, and a fucking MLO whips around the corner, shot to the head, that runs dead. Great! I love this! Fun! Quite joyous indeed! And what am I gonna do tomorrow? Right back at it! I am happy!

250 years of freedom, bitches 

The Borchardt C-93. The first mass produced Semi Auto / Autoloader pistol. It fires the 7.65x25 cartridge (around .30 in inches). Its auto-loading mechanism was revolutionary, however it was an ergonomic mess due to its vertical, 90 degree grip angle and rear heavy feel due to its design. Georg Luger was tasked with fixing this issue, however the arrogant Hugo Borchardt get his design was impeccable and impossible to improve upon, so Georg Luger bypassed him and redesigned it entirely. The P08 Luger changed the design and location of the recoil spring to make it less bulky and more ergonomic, plus better weight distribution, changed the grip angle, and shortened the ammunition to make the grip even more ergonomic. This cartridge was 7.65x21 Parabellum, however later when more stopping power was requested, the 9mm cartridge was born. Basically the Borchardt C-93 was the rough draft, the P08 Luger was the final.

List of every gun I own: 

OH FUCK hey some more actually showed up I forgot I made this 

The Glock 46. The one Glock (excluding the 44) that doesn’t share the same internal mechanisms as the others. It is a rotating barrel design, as you may have seen in guns like the Beretta Px4, GSH-18, and some 5.7x28 designs, such as the S&W M&P 5.7. It exists because German police requirements were for a gun that didn’t require a trigger pull to field strip, and a different trigger pull. The Glock 46 supposedly has a much longer trigger pull than usual. The rotating barrel, however, was apparently not required, and is unclear why Glock did that. It seems to field strip, this knob in the place of the backplate needs to be turned, and the magazine removed. Due to its unique takedown system, the usual Glock takedown levers are absent, leaving a smooth side. It seems to be the size of a Glock 19, with some photos showing extended magazines.

likely one of, if not THE first/earliest Glock prototypes. Notice how it looks nothing like current Glocks, indication this was more of a test, just throwing shit out there and seeing what works type of gun. Uses a takedown lever I am not familiar with, however the circular shape on the right side reminds me of P22X series SIG or S&W M&P. I can only seem to find two photos of this prototype (3 if you include the cropped and uncropped image of Katherine Glock holding it). Also notice how rough it looks around the takedown lever and beaver tail, further indication it being an early test prototype. Really the only thing similar to that of a modern Glock on it is the hooked shape of the trigger guard. I’m running out of ideas for this thread. 

Glock 26c 1-of-1 prototype. The Glock 26 was invented because of the 1994 gay gun ban whatever it was called, banning magazines over 10 rounds. Glock’s whole thing was high capacity, so limiting to 10 rounds meant there was really no point to the extra size of the 17 and 19, at least to the people conceal carrying, so Glock created the 26. The 26c didn’t make it however because the compensating cuts caused jams and intense, blinding fireballs with the 3.6” barrel. 

Is there a way to rename the forum
