Frequently Asked Questions

Can I convert my Smith & Wesson M&P 40 caliber to 9mm?

Yes, you can convert an M&P 40 caliber to 9mm by swapping the barrel for a 9mm version, such as one from Apex Tactical. It's also recommended to use 9mm magazines for optimal reliability.

Why are Apex Tactical barrels popular for M&P firearms?

Apex Tactical barrels are popular for M&P firearms because factory barrels can sometimes exhibit accuracy issues. Apex barrels are designed to improve lock-up and consistency, addressing these potential problems and enhancing overall firearm accuracy.

What are the common accuracy issues with Smith & Wesson M&P 1.0 and 2.0 models?

Some Smith & Wesson M&P 1.0 and 2.0 models can suffer from accuracy issues due to problems with the barrel's lock-up. This can result in inconsistent shot placement, where the firearm may not hit the same place twice.

Are 9mm magazines compatible with a 40 caliber M&P after a barrel swap?

While you can swap the barrel to 9mm, it's highly recommended to use dedicated 9mm magazines. Using 40 caliber magazines with 9mm ammunition in a converted M&P can lead to reliability issues.
