Description
The SIG Sauer P220 45 ACP CA is a pistol chambered in 45 ACP with a 4.4-inch barrel and a 8+1 capacity. This version is built to meet California requirements. It carries the build quality SIG Sauer is known for and is ready for carry, home defense, or the range.

SIG Sauer P220 45 ACP CA Overview
SIG Sauer’s classic hammer-fired pistols, including the P220, P226, and P229, earned their reputation with elite military and police units around the world. They use a smooth double-action first shot followed by light single-action shots, with a decocking lever to safely lower the hammer, or a single-action-only trigger on competition models. The rail-guided slide and robust frame make them accurate, durable, and soft-shooting.
Carry and Use
These pistols are heavier than polymer striker guns, and that weight works in your favor: recoil is soft, the sights settle quickly, and accuracy is excellent. They are favorites for home defense, duty use, and competition.
Trigger and Controls
The double-action/single-action trigger gives you a long, deliberate first pull and a short, light pull for follow-up shots. A frame-mounted decocker lowers the hammer safely without touching the trigger. Single-action-only competition models have a short, crisp trigger with a manual safety.
Sights and Optics
The factory sights give you a clear, fast sight picture for both precision shooting and quick defensive shots.
Caliber
The 45 ACP has served American shooters for more than a century. Its big, slower bullet hits hard with a recoil impulse many shooters describe as a firm push, and it remains a favorite for defense and competition.
Why SIG Sauer
