Your choice of .38 Special self-defense ammo could mean the difference between stopping a threat or going to the hospital. While the .38 Special is known for its accuracy and manageable recoil, not all ammo is created equal—some rounds offer better penetration, expansion, and reliability in life-or-death situations.
So, what’s the best .38 Special ammo for home defense?
We’ve done our homework to bring you the top-performing home-defense rounds, from the hard-hitting Hornady Critical Defense 110gr JHP to the ultra-reliable HOP Munitions 158gr JHP.
Hornady Critical Defense .38 Special +P 110gr JHP – Best Overall
Why It’s the Best
When your life is on the line, you need ammo that expands reliably, penetrates effectively, and hits hard. That’s exactly what Hornady Critical Defense .38 Special +P 110gr JHP delivers. This round is designed specifically for personal protection, featuring Hornady’s patented FTX bullet with a polymer tip that prevents clogging and ensures consistent expansion.
In short, this round does what you need it to do: stops the threat fast.
Key Specs:
- Casing: Brass
- Bullet Type: Jacketed Hollow Point (FTX)
- Bullet Weight: 110 grains
- Muzzle Velocity: 1,090 fps
- Muzzle Energy: 290 ft-lbs
Performance Breakdown
Hornady’s FTX bullet sets this ammo apart. The polymer tip helps initiate expansion on impact, which prevents over-penetration while maximizing energy transfer to the target. In a snub-nose revolver, where short barrels can reduce velocity, this round maintains enough speed and energy to ensure deep penetration—a key factor in self-defense effectiveness.
Pros & Cons
✅ Excellent Expansion: FTX bullet ensures consistent and controlled expansion, making it highly effective for stopping threats.
✅ Reliable Ignition: Clean-burning powder and high-quality primers ensure it fires when you need it most.
✅ Reduced Over-Penetration: The polymer tip helps prevent clogging, ensuring the bullet expands properly instead of passing through the target.
❌ Pricey: This is a premium defense round, so it’s not ideal for high-volume practice.
❌ Increased Recoil: Being a +P round, it has more recoil than standard pressure loads, which could be a factor for recoil-sensitive shooters.
Final Verdict
If you’re looking for the best overall .38 Special self-defense ammo, Hornady Critical Defense +P 110gr JHP is hard to beat. Its superior expansion, reliable ignition, and proven performance make it a top choice for personal protection.

Where semi wad cutter ?
Semi-wad cutters are like truncated cones…
Sniff, sniff. I smell ChatGPT.
In any event “muh stoppan powah” is a gun store commando meme. Stop spreading it. It’s unhelpful at best. And if it were a helpful term with a universally agreed-upon meaning it wouldn’t belong in the same sentence with “.38 Special,” for all the same reasons that five-shot fixed-sight wheelguns chambered for low-power, low-energy, low-velocity, low-pressure legacy blackpowder era cartridges do not belong in the same sentence with “home defense.”
Lucky Gunner has covered this subject in-depth and with the data for easy review:
https://www.luckygunner.com/labs/revolver-ballistics-test/
‘Airweight’ & ‘Ultralite’ snubnose revolvers with +P and .357 cartridges are more than a handful, there are other alternatives including Hornady 90 gr. Critical Defense Lite and the tried and true 148 gr. Winchester Super-X wadcutter.
Shootingthebull410 has a comprehensive short-barrel .38spl test series on YouTube…
The .38spl Taurus magnesuum “Hy-Lite” revolver in the photo is NOT +p rated for the ammo pictured next to it.
…. just sayin’
IMPORTANT QUESTION HERE: How long were the barrels of the guns that were used to produce these speed numbers? They seem awfully high, and that affects stopping power tremendously. Many ammo companies use compeletely unrealistic guns, sometimes with ten-inch long barrels.
Since there are 6″ and 4″ .38 Special revolvers, these numbers in your article might have come from testing with them. Thing is, almost nobody owns those anymore. People buy snubnosed .38s.
So … what were the barrel lengths in the testing that produced the numbers in this article?
Every bit as important as barrel length is barrel-cylinder gap! When I was QA Managger for Ruger’s Newport, NH operations the min. B-C gap before proofing was 0.003 pass / 0.004 hold. It is normal in a .357 for this to open 0.001 in proofing as the parts “set.” The desired Mean Assembly Tolerance after proofing was pass 0.005 / hold 0.006. Maximum acceptance for new guns to ship was pass 0.007 / hold 0.008″. At pass 0.008 / hold 0.009 the factory fix for an “open front gage” was to refit a “+” 0.005″ longer cylinder after correcting any end shake to bring the gun back into specs.
New Colts and S&Ws in your LGS are routinely shipped with B-C gaps of 0.010″ or more which produce 50-60 fps lower velocity than revolvers assembled to a 1980s Mean Assembly Tolerance. Loose B-C gap of 0.010 is entirely “within spec.”
The expected Delta-V firing standard-pressure, lead bullet .38 Special is 10 fps for each 0.001″ difference in B-C gap. This observation is routinely larger when firing jacketed +P, +P+LE or .357.
For this reason most JHP .38 loads fail to expand from barrels shorter than 3 inches UUNLES B-C gap does not exceed pass 0.006/ hold 0.007. A 2-inch snub assembled at minimum will chronograph faster than a 4-inch at max.
