The P227 Nitron Full-Size, Railed (R) configuration combines a 4.4 inch barrel with a 14+1 capacity in .45 ACP. It features a DA/SA action with a decocking lever and a spurred external hammer, using Browning-type short-recoil, locked-breech operation.
Construction emphasizes durability and handling: a stainless-steel slide finished in Nitron black over an aluminum-alloy frame with a hard-anodized black finish. The slide includes rear serrations and is non-optic-cut. The frame integrates a MIL-STD-1913 three-slot accessory rail for lights or lasers.
Sighting is straightforward and robust with fixed, dovetailed 3-dot sights (front single dot, rear two-dot) and a 6.3 inch sight radius. The barrel uses a 1:16 twist to stabilize common .45 ACP loads.
Controls and ergonomics include SIG's one-piece textured polymer E2 grip for a secure hold and consistent trigger reach. The DA/SA system with decocker supports confident administrative handling while maintaining a smooth transition between first and subsequent shots.
This pistol was manufactured in 2017, with the factory case label dated 14-Nov-2017 and SIG's catalog number 227R-45-BSS. Commercial production ceased around 2019, adding context for buyers seeking a well-kept example with complete factory packaging and a generous magazine set.
