Ahh, the Mystery of the RIA National Match 1911
Only produced for a single year by the Army’s Rock Island Arsenal, the RIA-marked National Match “GI Custom” 1911 .45 is a rare gun.
Why National Match?
So-called “National Match” 1911s date back to custom-fit target guns made to compete in the U.S. National Matches held annually, first in New Jersey and Florida and then at Camp Perry, Ohio. Modifications made by military armorers and famous Colt rep Henry “Fitz” FitzGerald to GI guns led Colt to introduce a specific National Match 1911 model in 1933, with lessons learned from the event guns. Except for the gap between 1941 and 1957, Colt National Match 1911s continue to be produced, in small numbers.


After World War II ended, with the Colt NM gun at the time out of production, the Army looked into making its own. The program, run out of the Army’s old Springfield Armory complex in Massachusetts, took existing GI M1911s already in inventory and re-worked them into more match-friendly guns. A National Match specification was established, and the conversion process included not only hand fitting and tuning but a new “hard” slide, either from Colt or Drake Manufacturing, while triggers, springs, bushings, and sights became an evolutionary process tweaked every season.



Between 1955 and 1967, Springfield Armory produced 24,055 NM M1911s, an average of about 1,850 guns per year. Of these, most were sent to assorted military marksmanship teams while just 3,876 were sold to the public through the Army-run Director of Civilian Marksmanship program, an organization that became the non-profit federally chartered Civilian Marksmanship Program in 1996.

However, with the Pentagon’s decision in the 1960s to close Springfield Armory as a money-saving measure (it would reopen in 1978 as a National Historic Site), it was decided that the Army’s in-house National Match program would shift its home to Rock Island Arsenal in Illinois.
The Short RIA NM 1911 Run
According to the FY1967 Rock Island Annual Historical Report, due to the planned phase out of Springfield Armory by the Army in February 1966, Rock Island sent two mechanical engineers and three armorers to Massachusetts to be trained specifically to support the National Matches.
Following five weeks of OTJ at Springfield, the Rock Island contingent worked side by side with Springfield Armory personnel at Camp Perry in the summer of 1966 while the tooling for the NM 1911 program shuffled from Massachusetts to Illinois. By September of that year, Rock Island officially received the Work Authorizations for the NM program, and the following month, the Army released the funds to proceed.
The program was authorized to complete overhauls on 1,533 caliber .45 M1911 National Match pistols, convert another 848 M1911 pistols to National Match standard, and overhaul 2,462 NM M14 rifles. However, the guns didn’t arrive at RIA until the end of 1966, while the technical data package was not received from Springfield until late January 1967. This put the program behind, and it wasn’t until March 1967 that a team of about 45 military and civilian armorers – many from marksmanship units from across the Army – had begun training, spread out in three, four-week classes, at RIA by the NM cadre instructors. It was only then that assembly began at the armory’s Building 61.
These original color photos were taken of the RIA NM 1911 line in Building 61 in June 1967, with armorers fitting pistols to precise National Match standards.






By July 6, 1967, 1,820 National Match M14 rifles and 1,764 NM M1911 pistols had been delivered to Camp Perry, notes the report. That August, nine RIA NM armorers went to the matches at Camp Perry to support the month-long effort there.
Then came the thunderbolt news that, with almost 500,000 U.S. troops stationed in Vietnam, the 1968 National Matches were canceled. It was the first time since 1950, when the matches were canceled during the Korean War, that Camp Perry would be shuttered for the summer. Further, the Gun Control Act of 1968 put a serious crimp on how guns were sold on the commercial market, one that is still felt today.
This brought about the end of the NM custom shop guns, with much more limited production shifted to the Army Marksmanship Unit’s Custom Firearms Shop, which continues to operate today.
Meet RIA NM 1911 #4784
The author was recently lucky enough to pick up a 4th Round Range Grade military surplus M1911 from the CMP.
A Military Model M1911A1 frame, serial number 824784, the pistol had been manufactured in 1942 at Colt. According to the CMP Forums, using the old Springfield Research Service books, it was accepted by the Army and shipped to Springfield Armory between September 18 and October 22, 1942. It likely went from there to an Army unit in Europe, as pistols in its serial number range soon after left for the New York Port of Embarkation.




Continued use?
Following likely use by a division, post, regional, Army, state, or other-level Marksmanship Training Unit, some signs point to #4784 being converted a second time since leaving RIA in 1967-68.


Doing the archival work, a FOIA request to the Army pulled the inventory records for the gun going back to 1975. It spent a lot of time at Fort Lewis, Washington, with “unknown” unit owners back when the 9th Infantry Division and 2nd Ranger Battalion were there. Sent to Anniston Army Depot in January 1989, it was soon turned around and sent to the Concept Evaluation Support Agency in Lexington (Bluegrass Army Depot) in October 1990, where it stayed for a few months before being sent to the 1st Cavalry at Fort Hood, then back to CESA in April 1992. Of note, CESA is the main supply depot for Army Special Forces and SOCOM units.

The pistol remained at CESA for almost 30 years, including the entire Global War on Terror. As the Program Executive Office for Special Operations Forces Support Activity (PEO-SOFSA) was at Bluegrass, the pistol may have been a loaner. Issued as needed and returned after a requirement, especially during the high-tempo SOCOM operations in the early 2000s, it may have never been “officially” transferred on paper. This could account for the OIF-era UIC sticker, Ergo Rigid grips, and straight main spring housing. Barring an email from some operator who remembers the gun and its serial, we may never know. Some GI NM 1911s have been documented as former Delta Force guns, and SF widely used accurized .45s for years post 9/11.
Sent to Anniston Army Depot storage in June 2020, #4784 was transferred to the CMP in July 2023. From there, it has just been in the Eger family collection and will stay there until its next chapter.
