Ipurchased my first Springfield Armory 1911 TRP many years ago.
It was the fulfillment of a longtime desire to own that flagship pistol from Springfield the one everyone coveted.
In addition, the pistol was also used by the FBIs highly respected Hostage Rescue Team (HRT).
The new Springfield Armory TRP AOS pistols are available in both .45 ACP and 9mm. Shown is the 9mm Carry Contour lightweight variant.
All the new pistols are built on the same solid foundation as all TRP pistols.
And lastly, except for the Carry Contour models, all the TRPs feature two-piece extended magwells.
The 4.25 Carry Contour (CC) models are probably the most radical deviation from the original TRP line.
AOS stands for Agency Optic System — the mounting system used by Springfield Armory to securely attach red dot sights to the TRP AOS 1911.
In all, there are eight new TRP AOS models offered in two primary configurations.
Now, there are a lot of new options for TRP fans.
So, lets dive into the details!
The new Springfield Armory TRP AOS pistols are fitted with Hydra G-10 grips from VZ Grips. They offer excellent purchase and long-term durability. A 5″ railed model is shown at rear, while a Coyote Brown 4.25″ CC model is up front. Image: Author
At that point, you will notice that the rear sight is dovetail mounted into a removable plate.
The 1911 TRP is now optics-ready!
(you’re free to find all the plateshereas well as a handy compatibility chart.)

It comes as close to having the optic be part of the forged slide as Ive ever seen.
Ive used several different-fitting optics with the AOS, and every one I have used co-witnesses perfectly.
Make Mine a Nine!
Shown here is the new Springfield TRP AOS with a number of AOS mounting plates. You have the option of running the factory iron sights or adding any number of popular red dots.
Affordability is another benefit of that chambering.
This makes the 9mm 1911 TRP a great option for those who prefer a more manageable round.
This, in turn, means follow-up shots can be faster, too.
This image shows how a pistol optic and mounting plate works together to affix a red dot sight to the slide of the new TRP AOS pistol.
For the 9mm, Springfield has re-engineered the gun a bit to optimize the cartridge and firearm mechanics.
The barrel has a fully supported ramp for both the 4.25 and 5 versions.
The full-size .45 holds eight rounds, while the .45 CC model packs in seven in its magazine.

Each pistol in .45 or 9mm comes with three magazines.
The 20-lpi checkering and VZ Grips, the 5-lb.
Gen2 speed trigger and ambi safety these are all shared across the TRP family.
The author got both the 9mm and .45 TRP AOS pistols out on the range during his review. In this image, he is shooting the Springfield Armory TRP AOS chambered for the .45 ACP cartridge. Image: Author
I fitted out both pistols with Trijicon RMR red-dot optics, mounted on the appropriate AOS plate.
This kept my sight picture consistent between both guns.
I fired a couple hundred rounds or more in all, with excellent performance.
The author found both the 5” .45 ACP and 4.25” 9mm versions of the 1911 TRP AOS to be accurate and reliable. Image: Author
It immediately felt familiar to my hands, reminiscent of my old personal 1911 TRP.
The big difference was that this one had an electronic sight on it!
Thats an advantage that wasnt even a fantasy back when I bought mine.
The new TRP AOS and its ability to accept red dot optics speaks to the resiliency and adaptability of the 100+ year old design. Image: Author
Having the AOS on a TRP is without a doubt a plus.
I rested the gun in a CTK Precision pistol rest and made use of the Trijicon optic.
With a minimum quantity of 25 rounds of each defense load tested, there were no malfunctions.
Range testing proved both the 5” .45 ACP and the 4.25” 9mm TRPs to be accurate and reliable. Image: Author
The nearly 40 ounces of gun feels well-balanced in the hand and makes the recoil feel smooth.
Next up, I performed all the same tests with the 4.25 CC TRP AOS in 9mm.
The shorter pistol isnt short on the TRP features by any means.
The author found the AOS option is the natural evolution of the legendary flagship Springfield Armory 1911 TRP.
The 4.25 CC has a short G.I.-style guide rod versus the two-piece full-size guide rod of the 5 guns.
It also has the bobbed grip frame shape.
I shot all the same accuracy tests with the 9mm pistol as I did with the .45 ACP.
Despite the shorter barrel, the results were remarkably good.
The average for all the shots tested was just a hair over one inch!
The best group of the day was made with Hornady Subsonic 147-gr.
XTP at less than 3/8 leaving just one ragged hole in the target.
And just as with the .45 ACP gun, the performance was excellent.
These two new changes to the TRP line are both highly significant.
Simultaneously introducing the 1911 TRP AOS 9mm is like having two front pages on the same newspaper.
