The MAC 9 DS 1911 by Army Armament Corp has been out since early 2024, however I lately received an opportunity to do an in-depth breakdown that I’ll now share with you. Mac 9 1911 DS or Double Stack is one other method of claiming Army Armament Company constructed their very own 2011. A few of you might consider STI, Infinity, Staccato, Prodigy, or others whenever you hear 2011, however the fundamental thought behind all of them is identical, a modular 1911-style pistol that has an ordinary capability of not less than 17 and may go up over 30 rounds with bigger magazines.
Beginning with the Sights
On this write up I’ll go over each half and facet of this pistol, and I prefer to go from the highest down beginning with the sights. The MAC 9 Double Stack comes with iron sights that characteristic a rear sight plate system. Every plate has a rear sight put in; the rear sight-only plate has a suppressor top rear sight with a Novak dovetail. This sight is made in a configuration that will permit the shooter to rack the slide one-handed if wanted.
The second plate has a Glock rear sight and is machined with the RMR optic footprint, each rear sights are fastened however may very well be changed with adjustable choices. The entrance sight is fiber optic additionally and includes a Novak dovetail in the event you select to switch it. One factor lacking from the entrance sight is blade serrations, it simply has a plain floor going through the shooter. The entire sights are suppressor or optic top suitable.
Match of the Gun
The slide, body, and barrel match are superb for a manufacturing gun. When dealing with a 1911 or 2011, the very first thing many individuals do is verify the match of the gun. Free match is considered low cost or sloppy and is usually unacceptable to most consumers. On the Mac 9 1911, there’s zero play within the barrel match and on the rear of the slide. On the entrance of the slide, there’s some left-to-right play, this space is the toughest to make good with zero motion. The information rod is a full-length rod that requires a small L-shaped device (equipped) to take away it from the slide. The information rod is hole, which is uncommon however could save a small quantity of weight.

The entrance of the gun displaying the muzzle, information rod, and reverse plug are normal wanting with the conventional match you can count on from a manufacturing gun. The mixing of the rear of the gun when the slide, body, extractor, ejector, and grip security come collectively could be very properly finished and presents properly to the shooter.
Slide Cuts and Options on the Mac 9 1911
The slide serrations and cuts are pretty normal, however paired with a Hello-Energy reduce on the entrance of the slide give the gun a contemporary look. The slide and extractor are a collection 70 design, the identical design JMB initially put within the 1911.

One other good contact on the slide is the bevel that was added to the entrance of the stripper rail. That is what strips the spherical from the journal, it additionally contacts the disconnector and pushes it down because the slide travels ahead throughout recoil. The bevel is a pleasant contact as a result of the slide will journey smoother over the disconnector.

Barrel Profile and Ramp Lower
The Mac 9 1911 barrel is a bull barrel that has the Clark/Para-style ramp to it. The ramped barrel is especially necessary because it has been confirmed to make the 2011 extraordinarily dependable.

The ramp on this gun appears to be set into the body additional than most different manufacturers. I consider that the ramp was reduce this option to mitigate potential interference with varied manufacturers of magazines. Some customized gunsmiths obtain the identical resolution by submitting the underside proper nook of the ramp on the barrel. I did measure barrel lug engagement and located .035 of engagement. There was no barrel springing discovered between the barrel and the slide.
Grip and Body of the Mac 9 1911
Transferring right down to the body and grip is what makes this gun considerably modular. In contrast to a 1911, the body and the grip are two items which are mounted collectively and secured with grip screws and a set off guard screw. The Mac 9 DS 1911 body follows the patterns of different widespread frames. Aftermarket grips, screws, and magwells will work with this body and grip. I used to be in a position to drop the body proper in a Cheely stainless-steel grip.

The MAC 9 DS does include a well-thought-out polymer grip. The set off guard has been undercut permitting for a pleasant and excessive grip on the gun. The traces are clear and the feel has really feel. Being polymer, the grip shall be straightforward to stipple to 1’s liking. Included magwell is low profile carry sort, and can work with base pads and longer magazines. The button on the magazine launch is considerably prolonged for straightforward operation.
Body Options to Know
The body has a 1913 picatinny rail on the mud cowl for gentle/laser setups. You will need to be aware that the grip security radius on the body is the .220 or Wilson radius. Most different 2011s have a .250 radius, so if one desires to improve the grip security, you’ll must order the Wilson fashion.
The grip security, or beavertail has an prolonged grip swell on it and solely must be depressed about midway in to be deactivated. So long as the shooter has considerably of an honest grip on the gun, the protection will work as supposed. Some grip safeties have to be pressed all the best way in, and that may be problematic for shooters with smaller arms.

My solely critique of the body is the vertical influence floor, it has a 90° nook on it and it ought to have a small bevel to it. This creates a aid the place the barrel and body influence one another below recoil and aids in final reliability.


Ejector, prolonged however not formed
The ejector within the body is an prolonged model, which is widespread for 9mm 2011s. It has a flat entrance that permits the brass to eject considerably randomly. It may very well be filed and fashioned to create a really constant ejection sample. The ejector can be put in with a roll pin fairly than a stable pin.

Ambi Security
This gun options an ambi thumb security. Match on it’s wonderful, and it goes on and off simply. The interface between the left and proper sides is one which I’ve not seen earlier than, nevertheless it did appear to snap collectively securely. The profile on the protection paddles is normal width, not both a slim carry or broad paddle by any means.

Fireplace Management System or Ignition of the Mac 9 1911
The ignition system on the Mac 9 1911 consists of the hammer, sear, disconnector, hammer strut, sear spring, and principal spring. All of those elements got here out of the gun and the match to the gun was effectively finished. The elements seem like drop-in as they don’t have any look of sharpening or enhancing.

The hammer hooks measured at .025 of an inch, which leaves room for shaping and dressing them. The sear additionally may very well be improved with some stoning.

The set off pull out of the field averages 5 kilos and 9 ounces. It’s a mean set off for a manufacturing gun, with a bit creep, however a decently clear break. Within the arms of a educated smith, this set off may very well be enhanced fairly a bit.

Set off tuning
The precise set off itself has a flat face and a pleasant look to it, the set off shoe is constituted of aluminum, and the bow from stainless-steel. The set off shoe on the set off is considerably lengthy for a manufacturing gun, when you have quick fingers it could have to be changed.

There may be an over-travel screw within the set off, nevertheless it was not set, the top consumer should do that. Additionally lacking is any sort of adjustment for ahead journey that almost all trendy 2011 triggers have. With ahead journey and over journey choices, shooters can fine-tune the texture of the set off to their desire.

Wrapping Up the Mac 9 1911
The varied spring weights I discovered had been as follows. 12-pound recoil spring, 19-pound mainspring, and 28 kilos of extractor stress.

See Extra: Taurus GX2 Evaluate (Taking pictures Video)The coating and end on the gun and small elements is a QPQ coating. This can be a very trendy and onerous coating that can forestall rust. The draw back to such a tough coating is making modifications to the elements is tougher on tooling.
This gun seems and seems like a 2011. It’s undoubtedly on par with different weapons in its value vary. Many of the elements shall be simply upgraded or interchangeable with different 1911 or 2011 elements. There are some well-thought-out options on this Mac 9 1911, particularly at this value level.
