40 S&W – 180 Grain FMJ – Remington UMC (L40SW3 / 23742) – 500 Rounds

The 180 grain bullet is the original 40 S&W weight and still the most common duty load, so practicing with a 180 grain full metal jacket gives realistic recoil. This listing is Remington UMC 40 S&W 180 grain full metal jacket ammo, MPN L40SW3 (Remington item 23742), sold as 500 rounds for owners of 40 caliber duty and carry pistols.

Remington lists this load at 990 fps with 392 ft-lbs of muzzle energy. That is a moderate velocity for the 40, offering a firm but manageable recoil impulse that closely matches 180 grain defensive hollow points. The full metal jacket bullet feeds reliably and stays clean in the bore. It does not expand, so it is meant for target practice, matches, and qualification rather than self defense or hunting.

This ammunition fits pistols and carbines chambered in 40 Smith and Wesson, including the Glock 22, 23, and 27, SIG P226 and P320 in 40, Smith and Wesson M&P40, Springfield XD, HK USP 40 and VP40, Beretta PX4, and the Beretta CX4 Storm and Hi-Point 4095 carbines. A common question is whether 40 S&W can be fired in a 10mm Auto pistol. It is not recommended. The 40 can chamber in some 10mm guns, but it headspaces poorly and can cause malfunctions or damage. Another common question is whether a 40 S&W pistol can shoot 357 SIG. Only after installing a 357 SIG barrel, because the two cartridges share a case head size but not a bullet diameter or case shape.

Remington L40SW3 is new production ammunition, not reloads, made in the USA. It uses reloadable boxer-primed brass cases and non-corrosive primers. This listing contains 10 boxes of 50 rounds for 500 total from one lot, so feeding and point of impact stay consistent through a full round of qualifications and the practice sessions that lead up to them.
