Best .45 ACP Pistols for 2025
1. Sig Sauer P220 – Best All-Around .45 ACP
The Sig Sauer P220 is often called a “gentleman’s .45 ACP” because of its refined design, excellent accuracy, and proven reliability. First introduced in the 1970s, it has stood the test of time and remains one of Sig’s flagship models for those who prefer a double-action/single-action (DA/SA) trigger.
Why We Recommend It:
The P220’s trigger system allows for a longer, deliberate first pull followed by lighter single-action shots. Its alloy frame keeps it lighter than some all-steel options, making it comfortable for extended range sessions. Many models include a de-cocker for added safety, and optics-ready versions are available for modern shooters.

Exceptional build quality
Great balance and accuracy
Proven reliability
Cons:
Lower capacity than polymer pistols
Higher price point
