Shooting Two Different Calibers in the Same Training Session

Published on November 15, 2025
Duration: 12:09

This video details a practice session involving shooting two different calibers (.40 S&W and 9mm) in the same training session, highlighting the process of converting a Smith & Wesson M&P 2.0 between calibers by swapping barrels and recoil springs. The instructor notes the recoil difference between the calibers and the impact of ammunition type on perceived recoil, while also discussing grip ergonomics and trigger performance.

Quick Summary

The Smith & Wesson M&P 2.0 can be converted between calibers like .40 S&W and 9mm by swapping the barrel and recoil spring. While lighter .40 S&W loads reduce recoil, they still snap more than 9mm. Ergonomic considerations, such as grip shape, may require increased support hand pressure.

Frequently Asked Questions

Can you swap calibers on a Smith & Wesson M&P 2.0?

Yes, the Smith & Wesson M&P 2.0 can be converted between calibers like .40 S&W and 9mm by swapping the barrel and potentially the recoil spring. The same slide and frame are used for both configurations.

What are the recoil differences between .40 S&W and 9mm?

Generally, .40 S&W has more recoil than 9mm. Lighter .40 S&W loads, like 125-grain frangible, reduce this difference but still snap more than 9mm ammunition.

Are there any ergonomic considerations for the Smith & Wesson M&P 2.0?

Yes, the M&P 2.0's grip can be narrower in the front and wider in the back, which may require users to apply more support hand pressure to maintain a stable connection during shooting.

What are the benefits of Apex Tactical modifications for an M&P 2.0?

Apex Tactical offers upgrades like barrels and extractors that can enhance the performance and reliability of the M&P 2.0, potentially allowing for smoother caliber conversions and improved trigger feel.
