1,350 FPS from a 1911? The DoubleTap 450 SMC

Here are the pictures of failed tested pistols :http://soldiersystems.net/2012/07/20/marsoc-winning-colt-guns/

The explanation http://karllippard.com/military/docs/45-ACP-Barrel-Safety.pdf

Karl Lippard’s 1911A2- The technology is century current and battle tested. The pistol is the most accurate 1911 known. For the purists that debate this point, try to shoot 400 & 600 yard shots with open sights with your prized Colt 1911, and land the shots on the target.

All metal parts of the gun, except for springs, are made of S7 ~ Vacuum Arc Melt Steel, certainly one of the strongest and best metal found in the world today. Tolerances are built at below .050 microns. That is a slide fit worthy of a Marine, say no more. In remote areas, the pistol’s instructions call to be cleaned with sand and any type of liquid (in battle, another way of saying urine) and you will be ready to go. It is guaranteed for life, guaranteed for life even if abused. Now there is an interesting concept here, guarantee for life, even if abused. Wouldn’t that produce a huge saving to the Military? One wonders.

The Lippard barrel will take pressures upwards of 78,000 PSI. In essence, you could very comfortable fire 460 Rowland cartridge pressures with his barrels and still have plenty of strength to handle the load. Most 1911 barrels don’t test at 1/2 of the tested pressures that of a Lippard, actually more like 21% but I was being generous.

History of the 1911 A2 Combat NCO® The proto-type “Combat NCO® Grade 1911 A1®” pistols were made in 1987-88 at Pachmayr Gunworks in Los Angeles, CA under the fine direction shop foreman Lester Pittman. A modified 1911 A1 they were called NCO’s and protected their otherwise Classified nature. The design and tactics for the Combat NCO originated from then General Manager of Pachmayr, Karl C. Lippard, former USMC Drill Instructor, Jungle Instructor and Hand to Hand Combat instructor who had combat experience using the 1911 A1 in an offensive mode.

These 1911 A1 series 70 pistols were modified to military specifications for specific combat use in small quantities.There were three types of pistols produced for the military. They were marked “NCO Grade Combat” in which a detailed criteria was given; an Officer Grade Combat in 9mm for military officers only; and General Grade Officer” .45 for General Grade officers only with their respective officer service number on the pistols.The NCO Grade pistols were requested by the Marine Corps for special unit use such as Force Recon, Delta Force and other special weapons units of the government for use against terrorists.

A manual was written to tactical engagement. Also designed for the criteria was a special knife made of A2 steel out of one solid bar. There were 27 knives made. It too was design specific to the military task of close quarter combat as taught by Marine Corps Hand to Hand Combat Instructors and Sgt. Lippard.All these military pistols and knives were warranted for life against everything from Pachmayr, including abuse. None that were made were ever been returned or seen again.

These pistols were made exclusively for the military and not sold to the general public until resurrected and updated in 2007. The Combat NCO knives and subsequent variations were sold and well known to the public. The knives were tested and used on combat operations by Karl Lippard’s old unit of 1st Force Recon and returned in 1999 upon retirement of the Unit Commanding Officer.The word “Combat” in the “Combat NCO” name is a statement of origin and identified it from common 1911 A1’s.

The acronym “NCO” in the name was used because he was the man who used it. The man and the pistol are both called Combat NCO’s. Born in Combat and tested there by Marines, Delta and CIA since 1987 the Combat NCO remains the only “Offensive use” 400 yard accurate military pistol designed for that duty in the world today.

Offensive Use Pistols in military service as a norm are defensive in nature. Specifically the 1911 A1 in discussion must be defined as defensive as it has none of the attributes to be used in an offensive mode. The sights are small giving poor results in most light conditions for accurate shooting at any distance beyond 10 feet for most users in a defensive mode. Its loose function made of 8620, and 4340 steel material allowed for functionality but limited its long term use, accuracy and survivability beyond the official life span of 16,000 rounds. Its redeeming feature however was the caliber of choice being the 45 ACP. In this it excelled in its assigned duty since 1911.

The Combat NCO®1911 A2® is an Offensive weapon by design.Before we can come to the designation of “Combat NCO, NCO or 1911 A2” model changes, we need to have a background on the differences from the 1911 A1. To even USE the term 1911 A2, or propose it, one would have to assume the original pistol in production designed by John Browning has been significantly modified in patent or design that improves the accuracy, economic life, function, effective range, interchangeability and military use of the A1. This has been done to such a degree that the 1911 A1 is not the same pistol except in conceptual thought

Some subsystems remain KLD classified even today. Furthermore, there are continued advancements in design for patent called the “A3 and A4” models taking the original 1911 out in upgrades to the end of this platform design set to be year 2100.These changes in the way barrels are made and replaced, it’s barrel bushing, nosepiece ~ bushing and it’s use; the slide stop, safety, hammer, sear, frame, slide, front sight, rear sight fixed, rear sight adjustable and, to include the material used, constitutes a “1911 A2” and acknowledges its origins.

Now that we possess accuracy and safety in the Combat NCO®1911 A2® we can think about for the first time extending its maximum range. And while this data is found in great detail in patent we can say here that the sights specific to the Combat NCO®allows it to give good results up to 400 yards. Some discussion there as to thickness of the front sight blade comes into play as it is an Offensive Weapon; how targets are measured in distance by that; how targets are engaged to maximum range if necessary, and in qualified hands, even extend the range from 400 to 600 yards without sight adjustment.

When all the criteria are satisfied of an accurate Offensive Weapon on a 1911 design platform, and all patented components are present, collectively it is called a Combat NCO®model 1911 A2®. It’s not who makes the gun that is important; but what’s inside it.

does anybody use 450 smc in standard m&p 45? what if any changes were needed?
