Events: which caliber for TAR, ISSF and TSV
| Caliber | TAR | ISSF 25 m centerfire | TSV (IPSC) |
|---|---|---|---|
| 9mm | Admitted | Admitted with lead bullets | Admitted |
| .38 Special | Admitted | Admitted | Admitted in Revolver |
| .357 Magnum | Loaded with .38 Special | Excluded | Admitted in Revolver |
| .45 ACP | Admitted | Excluded | Admitted |
| .22 LR | Excluded | Excluded | Excluded |
TAR, service-firearm shooting, admits centerfire handguns from 7.62 to 11.60 mm, with jacketed or plated projectiles; bare lead and wadcutters are prohibited7.
The ISSF limits 25 m centerfire to calibers from 7.62 to 9.65 mm, prohibits magnum-type ammunition and admits only lead or soft-material projectiles6. 25 m pistol, standard, rapid fire and 50 m are shot in .22 Long Rifle6.
TSV, practical shooting, follows the IPSC rules, which require a cartridge of at least 9 × 19 mm and a bullet of at least 9 mm in diameter8. The divisions are detailed in our article on IPSC and TSV.
Energy: .357 Magnum ahead, 9mm and .45 ACP level
Muzzle energy, by centerfire caliber
Manufacturer figures; the test barrel length changes from one caliber to another, and energy depends on it
9mm 124 grains, 150 mm barrel; .357 Magnum 158 grains, 150 mm; .45 ACP 230 grains, 127 mm9101112. The 158-grain .38 Special is measured with a 190 mm barrel13: in a revolver with a shorter barrel, it gives less.
View the data
| Caliber | Bullet | Energy | Test barrel |
|---|---|---|---|
| .357 Magnum | 158 grains | ≈ 760 J | 150 mm |
| 9mm | 124 grains | ≈ 518 J | 150 mm |
| .45 ACP | 230 grains | ≈ 504 J | 127 mm |
| .38 Special | 158 grains | ≈ 376 J | 190 mm |
9mm and .45 ACP deliver the same energy, around 500 joules, by two opposite routes: a 124-grain bullet at 360 m/s, a 230-grain bullet at 260 m/s91012. .357 Magnum reaches about 760 joules911.
That power comes from pressure: 3,000 bar in the CIP tables for .357 Magnum, 2,350 for 9mm, 1,500 for .38 Special and 1,300 for .45 ACP14151617. In sport shooting, energy scores no points: what changes is the feel of the recoil, sharp for 9mm, broader for .45 ACP.
Power factor: Major in .45 ACP and .357 Magnum
Calculated power factor, and the Minor and Major thresholds
Bullet weight in grains × velocity in feet per second ÷ 1,000, on manufacturer velocities
Thresholds from the January 2026 edition: Minor 125 in every division; Major 160 in Open, 170 in Standard, Classic and Revolver; no Major in Production, Production Optics and Optics8. In a match, the factor is measured by chronograph, in the shooter's own firearm8.
View the data
| Caliber | Load | Factor | Possible scoring |
|---|---|---|---|
| .357 Magnum | 158 grains at 395 m/s (1,296 fps) | ≈ 205 | Major in Revolver |
| .45 ACP | 230 grains at 260 m/s (853 fps) | ≈ 196 | Major in Standard and Classic |
| 9mm | 124 grains at 360 m/s (1,181 fps) | ≈ 146 | Minor; Major in Open with a hotter load |
| .38 Special | 158 grains at 271 m/s (889 fps) | ≈ 140 | Minor |
In TSV, power is measured by the power factor: bullet weight in grains multiplied by velocity in feet per second, divided by 1,0008. Minor starts at 125 in every division. Major, which scores more points on peripheral hits, starts at 160 in Open and at 170 in Standard, Classic and Revolver8.
In Standard and Classic, Major also requires a bullet of at least 10 mm8: .45 ACP qualifies, 9mm does not. In Open, no minimum caliber is set for Major8.

Pros
A .22 LR pistol remains a Category B firearm; only its ammunition is in Category C19. The detail is in our comparison 9mm or .22 LR.
.357 Magnum: a revolver that also fires .38 Special
The two cartridges share the same bullet diameter, .357 inch, and the same case head, 11.18 mm1516. The .357 Magnum case is about 3 mm longer18: a .357 Magnum revolver chambers .38 Special, a .38 Special revolver does not chamber .357 Magnum.
The TAR rulebook draws the consequence: « Les armes chambrées en 357 Magnum sont autorisées si elles utilisent la munition de 38 Spécial » [firearms chambered in .357 Magnum are allowed if they use .38 Special ammunition]7.
Which caliber for your event
What you gain, what you give up
For TAR and TSV with a single firearm, 9mm brings the lowest centerfire price per round. In return, it stays Minor in Standard and Classic.
For Major in TSV Standard or Classic, .45 ACP brings the required 10 mm bullet. In return, each round costs twice as much, and the ISSF is closed to it.
For precision revolver shooting, .38 Special brings the softest recoil and the ISSF wadcutter. A .357 Magnum revolver fires both rounds, at the price of a heavier firearm.
For the ISSF 25 and 50 meter events, .22 LR is the required caliber, at the lowest cost.
Three misconceptions about handgun calibers
- "9mm hits less hard than .45 ACP." Both deliver about 500 joules according to the manufacturer sheets1012.
- ".45 ACP is an Olympic caliber." 25 m centerfire is capped at 9.65 mm, and the other ISSF events are shot in .22 LR6.
- "A .357 Magnum revolver means shooting magnum loads." It also chambers .38 Special, the only ammunition admitted for it in TAR718.

Frequently asked questions
Which handgun caliber for sport shooting?
It depends on the event. 9mm is the cheapest centerfire caliber, €0.26 a round, and is admitted in TAR, in TSV and, with lead bullets, in ISSF 25 m centerfire. .38 Special serves precision revolver shooting, .45 ACP TAR and TSV, .22 LR the ISSF 25 and 50 meter events.
Is 9mm the cheapest caliber?
Among centerfire calibers, yes: €0.26 a round, against €0.44 in .38 Special, €0.50 in .357 Magnum and €0.56 in .45 ACP, by the entry-level box of 50. .22 LR drops to €0.13 by the case of 400 to 500, and €0.11 to €0.20 by the box of 50.
Can you shoot .45 ACP in ISSF 25 m centerfire?
No. The event admits only calibers from 7.62 to 9.65 mm; .45 ACP, at 11.43 mm, is excluded. Magnum-type ammunition is prohibited there, which also rules out .357 Magnum. .45 ACP remains admitted in TAR and TSV.
Can a .357 Magnum revolver fire .38 Special?
Yes. The two cartridges have the same bullet diameter and the same case head; the .357 Magnum case is about 3 mm longer. A .357 Magnum revolver therefore chambers .38 Special; the reverse is impossible. In TAR, a .357 Magnum revolver is admitted only with .38 Special ammunition.
What is the power factor?
In TSV, which follows the IPSC rules, it is the bullet weight in grains multiplied by the velocity in feet per second, divided by 1,000. The Minor threshold is 125 in every division; Major, which scores more points on peripheral hits, is 160 in Open and 170 in Standard, Classic and Revolver.
Which calibers are admitted in service-firearm shooting (TAR)?
Centerfire handguns from 7.62 to 11.60 mm, in their original caliber: 7.65 Browning, .38 Special, 9mm Parabellum, .45 ACP and others. Projectiles are jacketed or plated; bare lead and wadcutters are prohibited.
