- Polymer single-magazine pouch marked “SMP-06”
- Compact rail-mount red laser module

The 1911R’s stainless steel slide and frame are finished in SIG’s matte black Nitron coating, offering corrosion resistance and a low-glare profile. Forward and rear cocking serrations provide positive purchase for slide manipulation, while the 5-inch stainless barrel delivers classic 1911 accuracy.
A four-slot Picatinny rail is machined into the dust cover, giving instant mounting options for the included red laser module or other accessories. The Tac Pac bundle also supplies a SIG paddle holster and magazine pouch, so the pistol is ready for range or duty use right out of the case.
Shooter ergonomics are addressed with 25-LPI front-strap and mainspring-housing checkering, a flared magazine-well funnel for faster reloads, and double-diamond laminate wood grips wearing SIG medallions. A spare set of textured black panels is provided for those who prefer a slimmer profile.
Internally, the pistol uses a Series-80 style firing-pin safety and features a skeletonized three-hole trigger and commander-style hammer. Fixed white-dot front and rear sights complete the sight picture, delivering a clear, no-nonsense aiming system.
