P30 “Thursday”: Week Thirty-Two

19-Dec-09 – 13:35 by ToddG

74,067 rounds
10 stoppages, 0 malfunctions, 4 parts breakages

Such a busy week, we officially had to rename Saturday “Thursday Mk2.” Over four thousand rounds went downrange since the last update, and as you can see we’re just around the corner from the big Seven Five.

The trigger return spring broke after firing the very first round during my Monday practice session. That’s about 20,000 rounds since it was installed. The pistol was still shootable by manually pushing the trigger forward after each shot, but certainly not something you’d want to do under any circumstances. This is the second TRS that has broken earlier than the planned 25,000 round maintenance replacement. I believe there are two contributing factors. First, we know from long experience that high round counts over short periods of time play havoc on many brands’ trigger return springs due to heat, etc. Second, just like last time, this break occurred shortly after I’d had the spring out of the gun for detail cleaning and then struggled for half an hour getting it back in.

So there’s a very good chance that I’ve been weakening the spring with all of the pounding, twisting, and cursing to get it back in the gun. Nonetheless, I’d think about changing the spring every 10-15k rounds if I were carrying a P30 every day (which I am, so I will).

The American Eagle 124gr TMJ “Toxic Metal Free” ammo continues to be problematic. I’ve had a number of underpowered rounds this week and this little gem (pictured at right). Yes indeed, no primer. Came that way right out of the box. So that’s one mismanufactured bullet, three squibs, and one round with no primer — plus all the “light loads” — in about 13,500 rounds. Very unimpressive quality control, ATK.

Also, huge thanks to pistol-training.com contributor T.K. Ives for the do-it-yourself degausser he built from an old fan motor. I’m happy to say that the P30’s parts are no longer having a major impact on the Earth’s magnetic field, thus saving the planet from the solar disaster predicted by the Mayan calendar for 2012.

As you can probably guess, we’ll be doing the 75,000th round in the coming week. Look forward to a full report next Thursday. No really. Thursday. The real Thursday. I promise.

Train hard & stay safe! ToddG

  2. Mean Rounds Between Stoppage (MRBS): 7407
    90% Lower Confidence Level MRBS: 4807
    99% Lower Confidence Level MRBS: 3677

    Mean Rounds Between Failure (MRBF): 18517
    90% Lower Confidence Level MRFB: 9266
    90% Lower Confidence Level MRFB: 6383

    Went with new confidence levels this time. 80% is normally the lowest you want to go, but the gun has been running well enough to go with tougher standards (90 & 99).

  3. Whoops. That should say:
    90% Lower Confidence Level MRBF: 9266
    99% Lower Confidence Level MRBF: 6383

  4. how long before the degausser is available with the Pistol Training logo on it?

  5. Jason,

    How do the numbers compare to Todd’s final results with the M&P?

  6. I think I’m missing the joke about the degausser.

  7. Jesse — It’s not your fault. Rob has a problem converting his metric humor into English units.

  8. Todd,
    How does the accuracy of the gun compare from the first round fired to round number 70K? Have you noticed the wear on the barrel causing the gun to lose accuracy? I am sure that it is losing accuracy, just want to know how noticeable it has become.

  9. Regularguy — See the Week Thirty report. At 50,000 rounds — the last time a formal accuracy test was performed — the gun actually shot better than when it was brand new.

    By ToddG on Dec 20, 2009

  10. I would be interested in seeing the accuracy report once your reach 75K.

    By Regularguy on Dec 20, 2009

  11. weird how we use metric and you guys are the ones who fought the Brits?

    Definitely looking forward to the accuracy results after 75,000 rounds. That should be very interesting.
    I know you don’t reload Todd, but have you given any of your brass to anyone to how it handles being reloaded. The brass from the P30 seems to come out a little bit different than normal. With a bulge in the middle of the case. At least the brass I’ve seen from our prison guards guns does.

  12. SO!For you, M&P or P30?

    By JD on Dec 25, 2009

  13. Ok the ATK toxic free primer may not be manufactured to the best standards but your body probably is probably happy to avoid the heavy metals being pumped into it. 75k rounds–come to think of it you should get that heavy metal blood level checked out. . . .
