Barnes Defense, 9mm Luger, 124 Grain, Sierra JHP, 20 Rounds, Ammunition Barnes Defense 9mm Luger (part number 32529) pairs a 124 grain Sierra jacketed hollow point with the loading standards Barnes is known for. It is a standard-pressure load built for personal defense and everyday carry, packed 20 rounds to the box. If you want a proven lead-core hollow point in the most popular handgun caliber in the country, from an American company that has built its name on consistency, this is a straightforward choice. Why Buy It 124 grain Sierra JHP: a proven lead-core jacketed hollow point designed for reliable expansion. 1,090 fps and 327 ft-lbs at the muzzle: real defensive energy from a standard-pressure 9mm load. Standard pressure: no +P rating, so it suits any 9mm Luger handgun in good working order, from full-size duty pistols to compact carry guns. Brass cases: smooth feeding and extraction, and the cases are reloadable. Loaded by Barnes: assembled to Barnes' standards for round-to-round consistency. 20-round boxes: easy to carry, easy to store, and enough to confirm function in your own gun. The Bullet The 124 grain weight sits in the middle of the 9mm range, and many shooters consider it the balance point of the cartridge. It is heavy enough to carry momentum and penetrate well, yet it leaves the muzzle fast enough to expand reliably. The Sierra jacketed hollow point uses a lead core inside a copper jacket with an open cavity at the nose. On impact the cavity drives the jacket and core to open up, which widens the wound channel and slows the bullet so it puts its energy where it is needed. That is the basic idea behind every defensive hollow point, and this bullet has a long record behind it. The jacket also keeps lead off your bore and helps the bullet hold together as it expands. The tapered ogive and wide hollow point mouth are shaped to feed from a magazine without hanging up on the feed ramp, a key detail for any round you plan to carry. Ballistics Barnes rates this load from a 4-inch test barrel. Muzzle velocity is 1,090 fps with 327 ft-lbs of energy. At 15 yards it is still moving 1,055 fps with 307 ft-lbs, at 25 yards 1,035 fps with 295 ft-lbs, and at 50 yards 990 fps with 270 ft-lbs. The ballistic coefficient is .120. With a 25-yard zero, the bullet stays within about an inch of the line of sight out to 50 yards, so point of aim and point of impact line up across normal defensive distances. Barrel length, temperature and the individual firearm will change these figures a little; shorter carry barrels usually give up some velocity. Picking a Carry Load Any defensive ammunition should be tested in the gun you will carry it in. Run at least a couple of boxes through your pistol and magazines to confirm that it feeds, fires and ejects every time, and check where it hits compared to your practice ammunition. A 124 grain practice load with similar velocity makes a good training partner, since recoil and point of impact will feel much the same. Once it has proven itself, keep your carry magazines loaded with it and rotate the rounds out from time to time. This load works as well in a nightstand pistol as in an everyday carry gun. Standard pressure keeps recoil manageable, which helps with fast, accurate follow-up shots, especially in smaller pistols.
