Rifleman Review: Springfield Armory 1911 TRP 5" 10 mm RMR

posted on October 6, 2021

Springfield Armory's TRP line of 1911 handguns has been a popular line for the company for many years, and it has continually added new options to the lineup with different lengths, chamberings and extra features. Back in 2019, Springfield unveiled another addition to the line in addition to the 6" barreled 1911 TRP 10 mm RMR, the 1911 TRP 5" 10 mm RMR. As the name suggests, the TRP 5" 10 mm RMR is a shorter alternative to the long-side TRP 10 mm RMR, using a slide and barrel length similar to the classic Government Model profile that so many 1911 enthusiasts are familiar with.

Like its larger sibling, the TRP 5" is chambered for the 10 mm Auto cartridge, and comes with eight-round, single-stack, detachable box magazines. The 5" barrel is made of stainless steel with a Nitride finish, and features six-grove rifling with a left-hand twist rate of 1:16". Both the slide and frame are made from forged steel, and come topped off with Springfield's Black-T finish. With its all steel construction, the TRP 5" 10 mm weighs in a 44 ozs. empty with all other extra features mounted. With the standard Government Model profile, the TRP 5" has an overall length of 8.6" and a height of 6.4".

The two most noticeable extra features on the pistol are its iron sights and pre-mounted optic. As its full name suggests, the TRP 5" 10 mm RMR comes new in the box with a Trijicon RMR micro red-dot optic installed along with the proper mounting plate. It also comes with raised Trijicon tritium night sights, which offer a lower one-third co-witness through the objective window of the RMR. The front sight is dovetailed into the slide, while the rear sight is connected to the RMR mounting plate, and thus lacks its tradition dovetail mount.

Other features on the TRP 5" 10 mm RMR include enhanced controls and grip surfaces. The grip safety sports and extended beaver tail, and the thumb safety is also extended, as well as being ambidextrous. Both the hammer and trigger shoe are skeletonized for reduced weight and added aesthetic. Serrations are machined into both the front and back strap, which complements the green G10 serrated grips that the TRP 5" comes with standard. At the bottom of the grip, there is also and extended and flared magazine well insert for aiding with faster and more effortless reloads.

While both the 6" and 5" versions of the 1911 TRP 10 mm RMR are no longer actively offered by Springfield Armory, they can still be found in the wild. For more information on the rest of the 1911 TRP line that is currently offered, visit springfield-armory.com.
