How agencies judge duty ammo
The benchmark most people cite is the FBI protocol: shots into calibrated ballistic gelatin, bare and after barriers such as heavy clothing, wallboard, plywood, sheet steel and automobile glass. A penetration range of roughly 12 to 18 inches is commonly treated as the goal. Too little may not reach vital structures. Too much raises the risk to bystanders. Expansion and bullet retention matter, but penetration comes first.
The four loads
| Load | Design | Weights here | Known for |
|---|---|---|---|
| Federal HST | Jacketed hollow point, pre-skived jacket | 124gr +P, 124gr, 147gr | Very wide agency use |
| Speer Gold Dot | Bonded core | 124gr +P | Holding together through barriers |
| Hornady Critical Duty | FlexLock with InterLock band | 124gr +P | Designed for barrier-blind performance |
| Winchester Ranger T | Talon-style jacket | 147gr | Long service history |
124gr +P vs 147gr
The 124gr +P loads trade a bit of extra recoil and muzzle blast for velocity. The 147gr loads are heavier and slower. Many shooters describe their recoil as more of a push, and they often stay subsonic, which helps if you shoot suppressed. Both approaches have a long agency track record. What matters more is that the load runs reliably in your pistol and that your practice ammo has similar point of impact and recoil.
How to choose
- Agency first. Sworn officers generally carry what's issued.
- Function-test it. Run a meaningful quantity through your exact gun and magazines before carrying.
- Check +P approval for your pistol.
- Buy enough to be consistent. Keep the same load and lot where you can.

Frequently asked questions
What is the FBI ammunition protocol?
An FBI test series that shoots loads into calibrated ballistic gelatin, both bare and after barriers like heavy clothing, drywall, plywood, steel and auto glass. It's widely used as a benchmark, with 12–18 inches of penetration commonly treated as the target range.
124gr +P or 147gr?
124gr +P runs faster with slightly sharper recoil. 147gr is heavier and slower, often with a softer recoil impulse. Both are used by agencies. Choose what your gun runs and you shoot well.
What does 'bonded' mean?
The jacket is chemically or mechanically bonded to the core, which helps the bullet hold together through barriers. Speer Gold Dot is a well-known bonded design.
Can I carry +P in any 9mm?
Only if the manufacturer approves +P for your pistol. Check the owner's manual.
