Sig Sauer P220 220R45Bser2 45 4.4 Or 8R Blk

The Sig Sauer P220 is a full-size, single-action/double-action .45 ACP pistol built on a legacy spanning nearly five decades. Introduced in 1976, the P220 earned its reputation as one of the most inherently accurate .45 ACPs available, and it remains a trusted choice for defensive shooters, sport competitors, and professionals. This 2024 model arrives optics-ready out of the box—a significant practical upgrade that lets you mount a reflex sight to your setup without gunsmithing.

The P220 combines a stainless steel slide (finished in durable Nitron coating) with a lightweight alloy frame, keeping the overall weight at 30.4 ounces—manageable for all-day carry or range work. The 4.4-inch barrel and 7.7-inch overall length strike a practical balance between shootability and concealability for a full-size platform. You get SIG's proven four-point safety system: decocking lever, automatic firing pin safety, block safety, and trigger bar disconnector. The ergonomic one-piece polymer grip in black is checkered for control, and an integral rail gives you room for lights or lasers if you need them. Both front and rear slide serrations aid manipulation in and out of the holster.

From the factory, the P220 ships with SIGlite Day/Night sights, allowing you to pick up your sight picture in low light or darkness. The double-action/single-action trigger features SIG's short-reset trigger (SRT), making follow-up shots quicker than the standard version. You'll get two 8-round steel magazines in the box, giving you practical carrying capacity for defensive or training use. A manual safety is installed and engaged—your responsibility to understand and practice its operation before carrying the pistol.
