.40 S&W FAQs

Is .40 S&W still a good choice? Yes — it hits harder than 9mm with proven duty performance, and ammo plus used .40 pistols are often bargain priced.

165gr or 180gr? 165gr runs a little faster and flatter, while 180gr is the classic heavier standard-pressure load.

Can I shoot .40 in a 10mm pistol? No — the cases differ in length and the two are not interchangeable.
