1911 - 9mm vs 45 ACP

Published on May 23, 2020
Duration: 8:24

This Vickers Tactical video compares the 1911 platform in 9mm versus .45 ACP. Larry Vickers discusses magazine capacity differences, with 9mm holding 10+1 rounds versus .45 ACP's 8+1. He highlights recoil differences based on frame material, noting aluminum frames increase felt recoil, but 9mm remains softer shooting. Vickers also stresses the importance of ramped barrels for 9mm and aluminum frames, and proper extractor tension for 1911 reliability.

Quick Summary

The 9mm 1911 offers higher magazine capacity (10+1 vs 8+1 for .45 ACP) and softer recoil, especially in lighter frames. Ramped barrels are recommended for 9mm/10mm or aluminum frames to improve feeding reliability. Proper extractor tension is crucial for 1911s, particularly 9mm.

Frequently Asked Questions

What are the main differences between a 9mm and .45 ACP 1911?

The 9mm 1911 typically offers higher magazine capacity (10+1 vs 8+1 for .45 ACP) and generally softer recoil, especially with lighter frames. However, .45 ACP is known for its stopping power. Reliability can be affected by factors like barrel type and extractor tension, with 9mm often benefiting from a ramped barrel.

Does frame material affect recoil in a 1911?

Yes, frame material significantly impacts felt recoil. Lighter aluminum frames increase felt recoil compared to heavier steel frames. While a steel .45 ACP might shoot softer than a lightweight .45 ACP, a 9mm remains very soft-shooting even in aluminum frames.

What barrel type is recommended for 9mm or 10mm 1911s?

Larry Vickers recommends a ramped barrel for 1911s chambered in 9mm or 10mm, and also for those with aluminum frames. This design enhances feeding reliability by providing a smoother transition for the cartridge into the chamber.

How important is extractor tension for 1911 reliability?

Extractor tension is critical for 1911 reliability, especially in 9mm due to its smaller case rim. Improper tension can lead to feeding or extraction failures. Regular checks and adjustments are necessary for optimal performance.
