40 SW – 155 gr JHP – Black Hills (D40N120) – 500 Rounds

The 155 grain bullet is the fast, flat option in 40 S&W, and Black Hills has loaded it for years as a quality jacketed hollow point. This listing is Black Hills 40 S&W 155 grain JHP ammo, MPN D40N120, sold as 500 rounds. It suits armed citizens and agencies who still issue or carry the 40, and who want enough premium ammunition to qualify and practice with their duty load.

Retail specifications list this load at 1,150 fps with 455 ft-lbs of muzzle energy, which is among the higher energy figures for standard 40 S&W loads. The jacketed hollow point is designed to expand on impact and transfer energy, while the copper jacket helps the bullet hold together. The 155 grain weight gives a sharp but quick recoil impulse compared with 180 grain loads. This is self defense ammunition rather than general practice ammunition, though many owners do train with it to confirm reliability.

This ammunition fits pistols chambered in 40 S&W, including the Glock 22, 23, 27, and 35, Smith and Wesson M&P40 and M&P40 Shield, SIG P226, P229, P250, and P320, Springfield XD and XDM, Ruger SR40, and Beretta 96 and PX4 Storm. A common question is whether a 155 grain or a 180 grain 40 S&W load is better for defense. Both are proven weights, so pick the one that runs reliably in your pistol and that you shoot well under time pressure. Another common question is whether 40 S&W pistols can be converted to 9mm. Some models accept a factory or aftermarket 9mm barrel, but check with the manufacturer first.

Black Hills D40N120 is new production ammunition, not reloads, made in the USA in Rapid City, South Dakota. It uses reloadable boxer-primed brass cases and non-corrosive components. The listing ships as 25 boxes of 20 rounds for 500 total from one lot, a supply that lets you function test, qualify, and carry from the same production run.
