Building the 1911: Making the Nation's Favorite Handgun

Building the 1911: Making the Nation's Favorite Handgun

After all the hoopla last year concerning the 1911, you might have thought someone would have made a pilgrimage to the source to see how the gun was actually made after 100 years. No one has ever accused me of being punctual, so here's a little behind-the-times, behind-the-scenes tour of the Colt plant and what it takes to make a 45.

Colt is going through some big changes at the moment due to a massive investment in new machinery. Some machine tools have been in almost continuous operation at the plant since they were driven by overhead belts, and many are being replaced by state-of-the-art CNC machining centers, which is good for us consumers, as it usually means increased productivity, shorter lead times, more product choices and better quality. Despite all the changes, JMB himself would feel right at home on the shop floor and maybe just a little proud that his iconic design is still going strong.

Ready for Service

Raw forgings arrive from the foundry, ready for machine operations. There are other ways of making a 1911 frame, but beating red-hot steel with massive hammers has its own set of benefits. Besides, it's a manly way to make a manly gun.

Steel Grain

Like wood, forged steel exhibits a grain structure. When correctly oriented, this grain provides greater resistance to the shear forces generated when the pistol cycles.

Precision Frames

The 1911 frame requires many machine operations to complete, some of which are performed more efficiently on older tools. Here, the front strap and trigger guard are partially profiled.

Cutting the Channel

One of the most difficult operations to perform on modern equipment is cutting the channel for the trigger bow. The machines performing this operation have been in service since the plant first started making 1911s — as one is in use, the other is being rebuilt.

Heavy Lifting

Most of the heavy lifting is done on CNC machine centers like this one.

Processed Frames

Multiple frames are loaded into the machine and batch processed, saving time and handling.

On the Rack

The frames are placed on a rack together before the next step.

Engraving

Once fully machined and inspected, the frames are laser engraved with a serial number. At this point, a hunk of steel becomes a firearm.

Polishing

No machine is capable of handling the intricacies of polishing — a real, live and highly-skilled human is responsible for the final finishing of your 1911.

In-House Barrels

Barrels are produced in house on a CNC lathe.

Profiling the Barrels

After turning on the lathe, another CNC mill profiles the locking lugs and barrel feet.

Rifling the Barrels

Barrels are then rifled and chambered. Here, a rifling broach is seen next to the barrel it just produced.

Slides Forged

Slides also start out as forgings before making their way through the factory.

Hand Fitting

Once all parts have been manufactured, they come together for final hand fitting.

Approved By...

Once assembled and checked, the pistol is stamped on the trigger guard with the assembler's initial.

Proof Firing

Guns are then proof fired at the range before being boxed up and shipped.
