Frequently Asked Questions

Why is 9mm so dominant in the current handgun market?

The 9mm caliber dominates the current handgun market due to widespread adoption, manufacturer focus on producing 9mm firearms, and perceived effectiveness for self-defense. This trend is evident across various handgun models, including new releases in popular platforms like the 1911.

Are manufacturers abandoning calibers like .40 S&W?

Yes, manufacturers are increasingly phasing out less popular calibers such as .40 S&W. Examples include the HK VP9 series, which focuses solely on 9mm, and the diminishing availability of .40 S&W options in newer generations of popular pistol lines like the Smith & Wesson M&P.

Does bullet technology make 9mm superior to other calibers?

While bullet technology has significantly improved for all calibers, it doesn't exclusively make 9mm superior. Advancements benefit cartridges like .40 S&W, .45 ACP, and 10mm as well. The argument that 9mm is 'just as good' due to tech alone overlooks the inherent ballistic differences and the value of caliber variety.

What are the downsides of a market dominated by 9mm?

A market heavily focused on 9mm limits consumer choice and variety. Enthusiasts often appreciate different calibers like .357 SIG, .45 ACP, or 10mm for various reasons beyond basic self-defense, such as range enjoyment or specific performance characteristics. This lack of diversity can make the firearm market less interesting.
