Smith and Wesson and Winchester partnered to develop 40 Smith and Wesson ammo or the "40 cal" cartridge as a round for law enforcement. Their hope was to create a caliber that could mimic the performance of the FBI's reduced-velocity 10mm automatic round with rounds small enough in physical size to be carried with a medium-frame pistol.

40 S&W quickly caught on and remains a popular caliber for personal protection and range training today. Range shooters will likely opt for full metal jacket (FMJ) rounds with a non-expanding bullet while those seeking a round for protection will want to look at jacketed hollow point (JHP) ammo. In terms of ballistic performance, expect the lighter 40 cal rounds (155-grain) to leave the muzzle at about 1,205 feet per second and the heavier rounds (180-grain) to bring a muzzle velocity of about 1,050 feet per second.

Look for a wide selection of 40 S&W ammo for sale from trusted manufacturers like Federal, PMC and Hornady in the most common bullet types out there today, like full metal jacket (FMJ), jacketed hollow point (JHP) in the categories listed below:

    Ramps up slide perfectly into barrel no problems burns clean very little carbon build up my only gripe is firing pin issue not a bullet one so thumps up!

    This stuff in this grain is my winter carry ammo for self defense(due to heavy clothing in winter time needs more reliable consistent penitration), it doesn't comprise in consistency, it's hold really true for expansion and penitration, normally I like 180gr (just me I'm a go big grain or go home guy) but this in 165 beats the heck out of its 180gr brother in the same exact ammo. FYI my summer carry when I don't have to worry about heavy clothing on my attacker is the 180gr ranger t series (RA40T) best expansion your ever gonna see on a 40! But won't burrow as deep as these when it comes to clothing.
