  1. From match results published on uspsa.org, just aggregated.
  2. I'm showing the results for *all* classifiers. Some classifiers have distant partials, while others are easy. You can see from the charts that statistically speaking, people tend to shoot similar time, but same or better points in CO than Production on all of them. Sample size is big enough for it not to be a fluke. For classifiers where HHF is the same between CO and Production (everything before CM19-01) it means that it's objectively easier to get a given classification in CO, although not by much. There is no data on individual targets, but I find it hard to believe that on some kind of targets Production would give an advantage, yet you could not see it in the classifier level data. There are classifiers like "Can You Count" where red dot does not give any advantage, but classification is determined from *average* of six classifier results, so it's the *average* that counts.
  3. Yes, on average. Same time, better points, for all skill levels.
  4. November and December 2020 participation is clearly down compared to previous years.
  5. This is based on recent matches, Production division, before the 20 series became official. 99-11 was shot 3,833 times, the least popular classifier (99-59) was shot 165 times. Median is 1,300.
  6. The five most popular classifiers are: 99-11 El Presidente 06-03 Can You Count 13-05 Tick-Tock 18-04 Didn’t You Send The Mailman 18-07 Someone Is Always Willing To Pay
  7. I wasn't saying that it's safe to catch a falling gun. I was saying that letting it hit the ground is not always a safe thing to do.
  8. If it's a safety issue (and I'm not saying that it is), then it can be addressed by adding minimum trigger pull requirement. But it's a different story. Guns should not fire when dropped, regardless of how light their triggers are.
  9. I don't have that type of connection on Tanfos with factory firing pins. The firing pin does not protrude from the breech face when slide is locked back. Inserting a dowel into the barrel and pushing back on it does not move the hammer back. I thought extended firing pin has the same length, it just protrudes more from the back. If it is actually longer and can protrude both from the back and from the breech face then it certainly could pose a serious problem.
  10. Maybe for one gun, but not the other. There must be quite a bit of variability. I don't have a Shadow handy, but I checked three Tanfoglios (with factory springs) and see the same thing as in your GIF. The only difference is that Tanfoglios have firing pin block, so it should not be a problem. I still think that if the hammer is all the way forward, you won't be able to make the gun fire by hitting the hammer with a hammer.
  11. Your explanation makes perfect sense. Since the lowered hammer is not all the way forward, the rest of the discussion about bearings is unnecessary. The hammer hits the firing pin before the slide.
  12. I think this is the best explanation. The lowered hammer is not all the way forward, and the firing pin protrudes back from the hole in the firing pin stop.
  13. Yes they could. But for the gun to fire, the firing pin needs to move relative to the slide. The hammer needs to accelerate the firing pin differently compared to the slide. The difference in weight is not enough. If you put an empty can and a full can on a tray, then raise the tray up quickly, it's not like the empty can will fly higher.
  14. For the firing pin to move forward relative to the slide, the front surface of the hammer that is in contact with the firing pin needs to move forward relative to the slide. This can happen if a) the firing pin stop moves forward relative to the slide when hit by the hammer, even by just a little, or b) the hammer is not in contact with the firing pin stop initially, and the firing pin is protruding back from the hole in the firing pin stop. If the rear surface of the firing pin is initially flush with the rear surface of the firing pin stop, and the firing pin stop is all the way forward in its slot inside the frame, I don't see a way how the hammer can accelerate the firing pin more than the slide.
  15. The middle bearings are actually not at rest. Each one of them moves a little bit when hit, but the distance is small and it happens too fast for us to see. Imagine a hammer with a flat surface instead of the first bearing, and two large metal blocks to the left and to the right of the rest of the bearing stack, arranged so that they are flush with the second bearing. When you hit that contraption with the flat hammer, first bearing and both large metal blocks will move forward with the same speed.
  16. For that to happen, the firing pin spring (that pushes the firing pin and therefore the hammer back) needs to be stronger than the mainspring that pushes the hammer forward. Otherwise the hammer would rest on the firing pin stop, pushing it forward against the slide, and therefore not be able to push the firing pin forward relative to the slide when contacting the ground.
  17. 2020 Indiana Section Championship: Limited 46, Open 30, CO 27.
  18. And in August 2020, Carry Optics is the most popular division.
  19. If there are three GMs in your division at the Level II match and they place at 90% of the winner or above, you can get a classification bump. To get to C, you'll need to place at 45% of the winner or higher.
  20. To get classifier percent, your hit factor is divided by high hit factor for this classifier and division. The way USPSA determines high hit factor is not completely disclosed. For 19 series classifiers, it's the average of the top 10 results shot at 2019 Nationals where those stages were first introduced (except for Revolver, where they average fewer). For older classifiers, USPSA looks at historical data, throws out outliers (by some definition of outlier), then averages top-something remaining. Except for Carry Optics, where Production numbers are used instead.
  21. Seven weeks. Yes, cut out with scissors from some old plastic packaging. Seems to work fine, I ran a few thousand rounds with no visible shift.
