Best Ammo for the Glock 19, Organized by Use

A Glock 19 will eat almost anything in 9mm. That makes the choice about purpose, not compatibility.

Why use is the right way to sort

The Glock 19 has a reputation as the pistol that runs everything, and that reputation is mostly why ammunition advice for it gets lazy. If almost any 9mm will feed, then "which ammo?" reduces to "for what?" This page answers that three ways: the range load, the carry load and the bulk load. They are different tools, and mixing them up is the real mistake.

A note on method. These are editorial recommendations built from product specifications and common practice, not test results. Nothing here replaces firing a sample of a load in your own pistol.

Tier 1: the range load

For most trips to the range, Blazer Brass 115gr FMJ in the 300-round range bundle is the obvious general choice. It is factory-new, brass-cased full metal jacket ammunition. That has three practical advantages:

• Brass cases are accepted at ranges that restrict steel-case ammunition, and reloaders can reuse them.
• Factory-new manufacture means you are not inspecting each round for the quirks that come with remanufactured lots.
• 115gr is a long-standing practice weight for 9mm and generally produces a comfortable recoil impulse in a compact pistol.

If you carry 124gr or 147gr ammunition and want your practice to feel closer, the Blazer Brass 124gr bundle is covered in the 9mm range ammo comparison. The 9mm bullet weight guide explains what the difference actually does.

Tier 2: the carry load

Carry ammunition has a different job from range ammunition. It sits in a magazine for months, rides in all kinds of conditions, and should be a purpose-designed defensive hollow point. Federal's HST 124gr Battle Pack is one of the best-known options of this type, and it is a standard-pressure load, which sidesteps the +P question altogether.

A few points to keep in mind:

1. Test it. Run a box through your pistol and through each magazine you plan to carry. The point is not to find out whether it is a good bullet; it is to find out whether it feeds from your gun.
2. Keep the box. The lot number is how you check for recalls.
3. Rotate on a schedule. Many owners swap the top rounds of the carry magazine at regular intervals and shoot the old rounds at the range, though the schedule is a personal choice.
4. Don't mix. A carry magazine should hold only the carry load.

The Federal battle pack format is 250 rounds, which is far more than a single pistol needs for carry. That is fine if you plan to share with another household member or hold a reserve, but you might find it more practical to look at the defensive ammunition category for smaller formats.

The sibling site DefensiveHandgun has a 200-round checklist for a new defensive pistol that is worth reading before you commit to a carry load.

Tier 3: the bulk load

This is the tier that raises eyebrows, and it deserves honesty. Sportsman's Select 115gr FMJ in a 1000-round lot is remanufactured ammunition, built from previously fired cases. People buy it for high-volume plinking, and it fits that job when it is used with care.

The honest caveats:

• Lot variation. Remanufactured lots can differ more than new factory ammunition. Inspect what you shoot.
• Manual and warranty language. Read what Glock's literature says about remanufactured and reloaded ammunition before you build a habit around it.
• No defensive use. Remanufactured FMJ is for the range only.

If you do not shoot a thousand rounds in a reasonable period, this tier is probably not for you. Factory-new ammunition in a smaller quantity is simpler. For how reman fits in the bigger picture, see factory-new vs remanufactured.

A table to keep on the fridge

Questions Glock 19 owners ask

Which generation do I have? It matters less for ammunition than for magazines and parts. If you have an older Glock 19 and a newer one, read the manual that applies to each.

Do I need to clean differently with remanufactured ammo? Dirty ammunition is a fact of life for any high-volume plinker. Keep the pistol clean and lubricated, and check it periodically for wear.

Should I use +P? It is a manufacturer-approval question. The standard-pressure HST in this list avoids it. If you are curious about the +P option, the Federal HST comparison works through it.

Keeping the three tiers straight

The danger of a three-tier plan is confusion. A few simple habits help.

• Mark your magazines. Dedicate certain magazines to carry and keep them out of range bags.
• Store the tiers separately, in labeled containers.
• Rotate the carry tier on a schedule, and use the old rounds in a range session.
• Note any change to the pistol, such as a new barrel, spring or trigger part, and retest the carry load afterward.

Which is for you

• You shoot once a month and carry: one box of Blazer Brass for practice, and the HST for the carry magazine.
• You shoot weekly and carry: the 300-round Blazer bundle becomes your standard order. Revisit the carry load on a schedule.
• You shoot a lot and carry, and you are comfortable inspecting ammo: add the reman lot to the mix for casual volume.
• You do not carry: you may not need the HST at all, except for home defense. Choose based on your plan and your local rules.
