The excellent firearms reference website Modern Firearms is undergoing a major move to a new location, with a much improved interface and look. Although the new site is still in beta, it already appears to include most if not all of the pages from the original, in an attractive new updated format.

It’s no secret that the field of war is changing, and that fact is just as true for the infantryman as it is the F-35 Lightning II pilot. Increasingly, small, inexpensive, expendable drones are being used as intelligence, surveillance, and reconnaissance (ISR) assets, as well as delivery platforms for light ordnance as well as kamikaze weapons. Today, the use of drones in this manner is in its infancy, but the next generation of purpose-built light combat drones is being designed and built right now. Israeli firms like Duke Robotics and UVision have already created armed and kamikaze (respectively) drone systems, and combatants in the Iraqi and Syrian Civil Wars famously used drones as delivery platforms for 40mm grenades. The use of civilian light drones as “snooping” devices has already spurred the development of anti-drone weapons for security forces, including both electromagnetic “rifles” that zap drones to take control of them, as well as more crude (but still effective) anti-drone shotgun payloads.

In yesterday’s article, we took a look at examples of two different methods of design, which I called “preference-driven” and “process-driven”. For these examples, I supposed two engineers from two different cultures – called “Romulan” and “Vulcan” after the aliens from the Star Trek universe.* In the “Romulan” example, we explored preference-driven design, where a final product is outlined by amalgamating preferred characteristics from previous works to create a desired whole. For the “Vulcan” example, we examined the more elaborate method of developing processes that can be fed data to procedurally generate characteristics as an example of process-driven design.

If you were designing the next small arms round, how would you do it? What methods would you use to determine its physical characteristics and performance attributes? How would you know what was too large or too small, too powerful or too weak? Perhaps more critically, how do different methods for answering these questions compare to one another? Could some methods be better or worse than others?

The days of the Air Force‘s first stealth air superiority fighter, the F-22 Raptor, may already be numbered. US Air Force General Mike Holmes told Aviation Week that the requirements for the next-generation “Penetrating Counter Air” (PCA) program are taking shape. Although the F-22 remains the most advanced and capable fully operational fighter in the world, new foreign developments have emerged which may threaten its dominance. Specifically, the Russian Su-57 stealth fighter resulting from the PAK FA program, and the already in service S-400 Triumf (NATO reporting name SA-21 Growler) air defense missile system were cited by the General as being two systems that could potentially threaten the F-22. Therefore, a new fighter program is needed to maintain air dominance, according to the general.

The defense magazine European Security & Defence has published an article detailing for the first time Glock’s Modular Handgun System submission and its Federal-engineered ammunition. The article – part technical overview, part interview, details the recent history of Glock’s MHS submission, the technical characteristics of their Glock 19 MHS and 23 MHS pistols, and the current feeling among Glock executives about their second place finish in the competition. I highly recommend our readers head over the the ES&D website, where they can read the full article for free in text only or PDF form. But, since I don’t want to bury the lede any more than I have, here’s what Glock’s head of International Sales, Richard Flür, had to say on the Glock MHS’s future beyond the US Army:

Knight’s Armament Company has announced a new very light weight belt fed light machine gun – which they have appropriately termed the Stoner X-LMG (for “Extra Light Machine Gun). The new weapon is based on the previous Knight’s LMG, itself a development of the ARES, Inc (unrelated to ARES Defense, now called FightLite Industries) Stoner 86 LMG which itself descended from the famous Stoner 63 Light Machine Gun. Like those weapons, the new Stoner X-LMG is a 5.56mm caliber weapon, but unlike those it achieves a virtually unheard of light weight of just 8.6 pounds, unloaded. The release of the X-LMG was announced via IHS Jane’s, as well as – oddly enough – Turkish gear outlet Öztekin. From IHS Jane’s:

Manufacturers who are gearing up for the US Army’s Interim Combat Service Rifle competition better know where to get their ammo for testing, and the Army is ready to help. The US Army is facilitating the procurement of 7.62mm M80A1 ammunition to competitors for testing purposes, according to a new amendment to the ICSR solicitation. The amendment states that contractors can procure ammunition from either Orbital ATK (who operates Lake City Army Ammunition Plant), or Olin-Winchester. The process is described in the handy dandy flowchart below:

The SIG Sauer P320 – scion of the Army’s new M17 MHS pistol – is the only handgun out of eleven different weapons to fail a comprehensive test released today by Omaha Outdoors. The testing protocol involved dropping the handguns at different angles with a primed case in the chamber (no bullet or propellant). None of the ten other handguns – which included four Glocks, two H&Ks, two S&Ws and a 1911 – tested after the P320 fired when dropped. The video released by Omaha Outdoors describing the tests is embedded below:

The United States Marine Corps has issued a new acquisition notice for up to 50,814 M27 Infantry Automatic Rifles (IAR), to be sole sourced from Heckler & Koch. The notice is technically not a solicitation in and of itself, but a pre-solicitation notice, intended to give other companies the chance to submit their own proposals or bids if they think they can meet the same need at a lower cost. From the solication:

The following is the opinion of the author, and his alone. It does not represent the views of The Firearm Blog or any other TFB staff member. But I bet it represents the views of many of our readers.

Yes, the M4 Carbine will be replaced by a 7.62mm Interim Combat Service Rifle, and also no it won’t. Ah, I see I need to explain.

Those who take advantage of SIG’s recently announced “voluntary upgrade” may soon be taking home a little piece of the Modular Handgun System program: The company evidently plans to introduce a new trigger design developed for the MHS program as part of the upgrades, as relayed in a recent article published by Eric Graves over at Soldier Systems Daily:

The traditional wisdom goes: Lightweight or “pencil” profile barrels can shoot great – just so long as you don’t get them hot. After a mag or two of heat is dumped into your lightweight build, your point of impact (POI) will probably shift by several minutes of angle. If you don’t like it, then you’d better go for a thicker profile or learn your holdovers, because that’s just a fact of life with pencil-thin tubes.

It has been a little while since we visited the subject of modern personal defense weapon calibers, so to start it off again we’ll be taking a look at a new high velocity round that is only a few years old: Armscor’s .22 TCM. This round was reportedly developed by Fred Craig as a high velocity caliber for the 1911 platform, and picked up by Philippine company Armscor. Originally called the “.22 Mini Mag”, the .22 TCM (Tuason-Craig Magnum, after Craig and Armscor’s president) is designed to fit inside the magazine well of a 1911 and function from .38 Super 1911 magazines. Although a pistol round, the .22 TCM is based off the .223 Remington case, shortened by about three quarters of an inch. Thanks to the thick web of its parent case, the .22 TCM is capable of handling high pressures of 40,000 PSI. A version with a shortened projectile, the .22 TCM 9R, is compatible with shorter 9mm magazines for weapons like the Glock 17.
