About This Firearm
The TRP (Tactical Response Pistol) is Springfield's top-tier production 1911, built to replicate the FBI contract gun. At 42 oz, it is the heaviest .45 ACP 1911 in this lineup, 4 oz above the Kimber Custom II and 2 oz over the Springfield Loaded. That mass pays off in recoil absorption, and owners consistently report the TRP shoots noticeably flatter than lighter 1911s. The 4.8 lb single-action trigger, Cerakote finish, G10 grips, and forged steel construction throughout put it in Dan Wesson Specialist territory for build quality.
One practical note: the TRP ships with two magazines. Given the 7-round capacity and the gun's role as a duty/defensive 1911, that second magazine matters. The front strap checkering is 20 LPI, aggressive enough for a positive grip in wet or gloved conditions. Reviewers note the TRP typically needs little to no break-in period, which is unusual for a 1911 at any tier.

Strengths & Limitations
- Built to replicate the FBI's Professional Model 1911. The Cerakote finish, G10 grips, and 20 LPI front strap checkering are all carry-specific features that most 1911s require custom shop work to add.
- At 42 oz, it is the heaviest production .45 ACP 1911 in this lineup. That weight absorbs recoil noticeably better than 37-38 oz alternatives.
- The 4.8 lb single-action trigger and forged steel throughout put it in the same build-quality tier as the Dan Wesson Specialist at 42.3 oz.
- Seven-round capacity with no rail. For a duty-oriented gun, the lack of a light rail means you need a separate handheld light or an adapter.
- 42 oz loaded weight makes it one of the heaviest .45 ACP options for daily carry. Owners report needing a dedicated gun belt to manage it comfortably.

Frequently Asked Questions
What does "TRP" stand for and what is the FBI connection?
TRP stands for Tactical Response Pistol. Springfield designed the original TRP to meet FBI specifications for their Hostage Rescue Team's 1911. The civilian version retains the same features: tritium sights, Cerakote finish, aggressive checkering, and hand-fitted internals. The Bureau later moved to other platforms, but the TRP spec has remained unchanged.
What kind of holster works with a full-size 1911 that has no rail?
Any holster made for a standard Government-length 1911 with a 5" barrel will fit the TRP. The 1.25" width and 8.6" overall length are standard 1911 dimensions. Holster makers like Milt Sparks, Comp-Tac, and Safariland all have 1911-specific options. Avoid holsters designed for railed 1911s, as the TRP's dust cover is flush.
