What does ACP stand for?

I’m sure most everyone here already knows the answer but for the one or two that may not I found this interesting........

ACP Automatic Colt Pistol.... but it's really a term for ammunition, not a pistol.  

Rimless ammunition that feeds in magazines and auto pistols better than rimmed.

And used in many more pistols than Colt (thank goodness).  Besides his own company (Browning) and Colt, he did business with many more firearm companies.  

I already knew about the genius John Moses Browning.   (120 firearm patents)  One of my favorite men in world history.

Think about designing a pistol that was the US military sidearm from 1911 to 1986, and machine guns in .30 and .50 to this day (with minor mods).

Try to think of other (important) original inventions that remain largely unchanged, and in common use, for over a hundred years.

And then there was the Gatling Gun which was first used in 1860 during the Civil War. 
And now...  the Minigun which is the great, great, (well, you get it) offspring of the Gatling gun.
One of the most fearsome weapons used in combat!

The M134 Minigun is a 7.62×51mm NATO six-barrel rotary machine gun with a high, sustained rate of fire.
It features a Gatling-style rotating barrel assembly with an external power source, normally an electric motor. Wikipedia
Caliber: 7.62 mm
Maximum firing range: 3,280 ft (1,000 m, 1,093 yd)
Rate of fire: Variable, 2,000–6,000 rpm
Barrels: 6
Designer: General Electric
Manufacturer: General Electric, Dillon Aero, Garwood Industries, Profense
Cartridge: 7.62×51mm NATO

And the three barreled .50 BMG version!

The GAU-19/A, is an electrically-driven heavy machine gun that fires the .50 BMG cartridge. Wikipedia
Length: 4′ 6″
Barrel length: 36″
Action: Electric
Designer: General Electric
Maximum firing range: 6,000 m
Rate of fire: 1,000, 1,300 or 2,000 rounds per minute
Feed system: linkless or M9 linked belt

Sorry.  Didn't intend to change the subject.  Just watched a video on the GAU and had to share info.

Jess,
Hieronymus Mueller, he actually began in the firearms business in 1857. His focus turned to plumbing goods in 1880. Though he shifted manufacturing to aid both World Wars. In 1871 he invented the Mueller Tap Machine. A tool that allows you to install a new water service on a live pressurized water line. For the most part has been virtually unchanged. I have done more water taps than I can count and to this day, every time I use it, it still amazes me. Like J. M. Browning, Mueller's accomplishments are many, 501 patents. I admire both and enjoy reading their history.

That is interesting.  

I suppose their are many inventions that have been around (mostly unchanged) for a long long time.

Like the wheel.  And the boat.  And the shoe.  

It's also interesting how firearms really lead the way in metalworking technology, for better/stronger metallurgy, for precision machining, and for repeatablity of parts production.  Of course, the king, duke or emperor in charge of the public funds, pushed for development of the best means to secure his fiefdom and power, and to advance his power against his enemies, once they discovered firearms in hands of the common man with fairly simple training could stand up to and defeat professional knights in armor with swords and spears on horses.

With regard to modern plumbing, it's also interesting to note that men (and even kings) carried rifles for several hundred years while they were still shitting in their backyards, and streets, and drinking water.

... Though he shifted manufacturing to aid both World Wars. ...

LOL!  You've got him running his company past 100 years of age.  He was a very amazing man but was actually gone before either World War.  His company did indeed provide manufacturing support for both wars.
