Power Factor for Various 9mm Factory Loads

If you’re running into reliability issues with your 9mm pistol there are 3 likely causes:

  1. You’re shooting wrong
  2. There’s something wrong with your gun
  3. The ammo you’re running doesn’t have enough power to cycle the gun

The first two points are a a blog post all their own, but the third point is easy to fix:

Shoot hotter ammo.

Note: I don’t warranty the correctness of this data, please only use it as a general guideline.  Do NOT use it to determine if a particular load meets power factor for any competition you shoot.  

This data is a work in progress which I’ll update as I find more information.

The Power Factor Formula is:

Power Factor = (Bullet Weight X Muzzle Velocity) / 1000

Many competitions use it to determine if a shooter’s ammunition meets the criteria for the shooter to compete.  A general thought is that lighter loads MAY give a shooter an advantage due to reduction in recoil, although in reality, lighter loads also potentially mean reduced reliability – so it’s very much a trade off:

You may take off 0.05 from your splits, but you may also add 3 seconds from having to clear a stoppage.

Regardless, outside competition, power factor may also be handy to troubleshoot problems your gun may be having.

If you are encountering systemic reliability issues with your gun, my recommendation to figure it out (in order) is:

  1. Check your technique,
  2. Change your ammunition to something with a higher power factor,
  3. Attempt to troubleshoot of the gun within your level of confidence,
  4. Have the gun serviced by a certified gunsmith

The kind of problems you may have include that may merit changing ammunition

  • Failures to extract spent casings
  • Failures to feed new rounds in between shots
  • Failure to slide lock on last round

I encountered all of these problems running my Poor Man’s Roland Specials (shown above), and I’ve concluded I likely need a minimum 140 PF to run those guns.

See you on the range… hopefully with some hotter factory loads and a lot less TRB’s!
