Description

DoubleTap 9mm 124gr Low Flash JHP ammunition is DoubleTap’s +P 9mm carry load built on a 124 grain Controlled Expansion jacketed hollow point. It uses low flash powder, so you keep more of your night vision after a shot, and it balances solid penetration with dependable expansion. DoubleTap calls it a middleweight load, sitting between fast 115 grain rounds and heavy 147 grain loads. Each box holds 20 rounds.

A Middleweight +P Load for Everyday Carry
The 124 grain bullet weight is a favorite among 9mm carriers for good reason. It gives a bit more mass than 115 grain loads for steadier penetration, but it still moves fast enough to expand reliably from compact barrels. DoubleTap loads this one to +P pressure to get the most out of the Controlled Expansion JHP without going to extremes.
DoubleTap lists about 1,310 feet per second and 473 foot pounds from a full size Glock 17, and about 1,295 feet per second and 462 foot pounds from a compact Glock 19. That small drop between barrel lengths shows how efficiently the powder burns, which is good news for anyone carrying a mid size pistol.
The Controlled Expansion hollow point is designed to open consistently and hold together, rather than fragmenting on contact. Combined with low flash powder, it makes a smart choice for home defense and concealed carry, where a bright muzzle flash in low light can be disorienting.

Field Notes and Carry Tips
Because this is a +P load, use DoubleTap 9mm 124gr Low Flash JHP ammo only in pistols that the manufacturer rates for +P ammunition. Most modern polymer and steel frame 9mm pistols qualify, but check your owner’s manual, especially with older or very lightweight guns.
Run at least 50 to 100 rounds of your carry ammunition through your pistol before trusting it, including a couple of full magazines of this exact load. Confirm it feeds from every magazine you carry, ejects cleanly and lands where your sights say it will at typical defensive distances.
Rotate your carry rounds every few months, and avoid chambering the same round over and over, which can push the bullet deeper into the case. Keep a spare box on hand so you can practice with the same load you carry.
If you want a well balanced 9mm defensive round that performs from both full size and compact pistols, DoubleTap 9mm 124gr Low Flash JHP is a proven pick for your carry gun and nightstand. Pair it with snap caps for dry fire practice and a magazine upgrade for faster reloads.
For home defense, keep a loaded magazine of this ammunition in a quick access safe and a light mounted or within reach. A 124 grain +P hollow point offers a good balance of penetration and control for most adult shooters, and the low flash powder helps you keep your sight picture if you ever need a follow up shot in a dark room.
Store unopened boxes in a cool, dry place away from solvents and oils. Properly stored centerfire ammunition stays reliable for many years, so buying a few extra boxes now keeps your practice and carry supply consistent.
