.38 Special Ammo: The Best Proven Guide
.38 Special has been in continuous production since 1898, making it one of the longest-serving handgun cartridges in American history — the standard police service round for most of the 20th century before semi-autos took over, and still one of the most popular revolver chamberings today. It’s also, as we covered in our .357 Magnum guide, the parent cartridge .357 Magnum was built from. Here’s what actually matters when buying it.
.38 Special Ammo: Standard vs +P
This is the most important buying decision in .38 Special, and it’s a pressure question, not a caliber question — similar in spirit to 5.56 vs .223, though the mechanics differ. Standard-pressure .38 Special is loaded to a lower maximum pressure and is safe in essentially any firearm chambered for the cartridge, including older or lightweight revolvers. .38 Special +P is loaded to a higher pressure for improved velocity and terminal performance, but not every .38 Special revolver is rated for it.
Check your specific revolver’s rating before making +P your default carry load. Many older revolvers, and some modern lightweight (aluminum or scandium-frame) models built primarily for concealed carry, are not rated for sustained +P use — firing occasional +P may be listed as acceptable while high-volume +P practice is not, so read your specific manufacturer’s guidance rather than assuming.
.38 Special Ammo: Grain Weight Guide
| Grain Weight | Best For |
|---|---|
| 110–125 gr | Common +P defensive weights, higher velocity |
| 130 gr | Standard-pressure FMJ, the traditional target/practice load |
| 148–158 gr | Classic target wadcutter and standard-pressure loads |
158gr standard-pressure round nose or semi-wadcutter is the traditional .38 Special load, still widely available and a reliable choice for practice in any .38 Special-rated firearm. For carry, 110–125gr +P JHP (in a revolver rated for it) is the more commonly recommended modern defensive option, trading some bullet weight for meaningfully improved expansion and velocity.
.38 Special Ammo: Snub-Nose vs Full-Size Revolvers
Barrel length has an outsized effect on .38 Special performance compared to many other calibers, because the cartridge’s relatively modest powder charge means a shorter barrel (common in 2″–3″ snub-nose carry revolvers) gives the powder meaningfully less room to fully burn than a 4″+ service or target revolver. This is why some +P loads specifically marketed for snub-nose revolvers exist — engineered and tested to expand reliably at the lower velocities a short barrel actually produces, rather than at the velocities the same load would reach from a longer barrel. If you carry a snub-nose .38, look specifically for ammunition tested from a comparable short barrel length, not just generic +P performance figures measured from a 4″ or longer test barrel.
.38 Special Ammo: .38 Special vs .357 Magnum
We covered the full mechanical relationship in our .357 Magnum guide, but the short version: .357 Magnum’s case is physically longer than .38 Special’s, specifically so it cannot be chambered in a .38 Special-only revolver. A .357 Magnum revolver can safely fire both .357 Magnum and .38 Special — many .357 owners use .38 Special (including +P) as their primary practice and even carry round, reserving full magnum loads for situations where the extra power is worth the recoil.
.38 Special Ammo: Which Should You Buy?
Choose standard-pressure 130gr or 158gr if you:
- Are training fundamentals or shooting high volume at the range
- Own an older revolver, or one not rated for +P
- Want the lowest-cost, mildest-recoiling option
Choose +P 110–125gr JHP if you:
- Are carrying a modern revolver specifically rated for +P
- Want improved terminal performance over standard-pressure loads
- Own a snub-nose and are using a load specifically tested from short barrels
Choose 148gr wadcutter if you:
- Are shooting formal target competition, where wadcutters are the traditional, purpose-built choice for clean scoring holes
Common Buying Mistakes
- Running +P ammunition in a revolver not rated for it, especially older or lightweight carry-focused models. Confirm your specific firearm’s rating first.
- Buying generic +P defensive ammo for a snub-nose without checking short-barrel-specific testing. Performance figures from a 4″+ test barrel don’t reliably predict what happens from a 2″ snub-nose.
- Assuming .38 Special ammunition is universally interchangeable across every .38-chambered firearm without checking that specific firearm’s +P rating.
- Overlooking recoil differences between snub-nose and full-size revolvers when choosing a carry load — the same load can feel meaningfully sharper out of a lightweight snub-nose.
What Experienced Shooters Commonly Recommend
- Most recommended carry load for a rated snub-nose: +P JHP specifically tested and marketed for short-barrel performance, rather than generic +P figures.
- Most recommended for practice: standard-pressure 130gr or 158gr, cited most often for cost and reduced recoil fatigue over a long range session.
- Most common problem reported: disappointing terminal performance from generic +P ammunition fired from a snub-nose, resolved by switching to a load specifically tested and marketed for short barrels.
- Most common myth debunked in community discussion: that any +P .38 Special load is automatically safe in any .38 Special revolver — always confirm the specific firearm’s rating.
.38 Special Ammo: Storage & Maintenance
Store .38 Special ammunition cool, dry, and out of direct sunlight — properly stored factory ammunition can remain reliable for decades, with humidity posing the real long-term threat to primers and powder rather than age alone. Revolvers generally have simpler mechanisms than semi-autos, but they still benefit from regular cleaning of the cylinder face, forcing cone, and barrel to clear lead and powder fouling, which can affect cylinder timing and accuracy if left unaddressed over a high round count — particularly with lead (non-jacketed) practice loads, which tend to foul more than jacketed ammunition.

You must meet all legal requirements to purchase, and ammunition cannot be shipped to every jurisdiction.
Frequently Asked Questions
Is .38 Special +P safe in any .38 Special revolver? Not necessarily — many older or lightweight revolvers are not rated for sustained +P use. Always confirm your specific firearm’s rating before making +P your default load.
What’s the best .38 Special ammo for a snub-nose carry revolver? +P JHP specifically tested and marketed for short-barrel performance, since generic +P figures are usually measured from longer test barrels and may not reflect what a 2″ snub-nose actually produces.
Can I shoot .38 Special in a .357 Magnum revolver? Yes — this is standard, safe, and common practice, and many .357 Magnum owners use .38 Special as their primary practice round.
What’s the difference between standard .38 Special and +P? +P is loaded to a higher pressure for improved velocity and terminal performance, but requires a firearm specifically rated for it — standard pressure is safe in essentially any .38 Special-chambered revolver.
Is .38 Special good for self-defense? Yes, particularly with a modern +P JHP tested for your specific barrel length — it remains a widely carried and well-regarded defensive cartridge, especially in compact revolvers.
Why does barrel length matter more for .38 Special than some other calibers? Its relatively modest powder charge means a short barrel gives it meaningfully less room to fully burn than a longer one, which is why short-barrel-specific ammunition testing matters more here than for some higher-pressure cartridges.
What’s a wadcutter and when should I use one? A wadcutter is a flat-nosed target bullet designed for clean, easily-scored holes in paper targets — the traditional choice for formal .38 Special target competition, not a general-purpose or defensive round.
Is .38 Special being phased out by manufacturers? No — despite being over a century old, it remains in active, widespread production and is still one of the most popular revolver cartridges sold today.
How long does .38 Special ammo last in storage? Properly stored (cool, dry, sealed) factory ammunition can remain reliable for decades. Moisture and temperature swings threaten shelf life far more than age alone.
Does lead .38 Special ammo foul a revolver more than jacketed ammo? Yes, generally — unjacketed lead bullets tend to leave more fouling in the barrel and forcing cone than jacketed ammunition, so revolvers shot heavily with lead loads benefit from more frequent cleaning.
