  1. I'm pretty sure Trijicon RMR (original, with no electronics) can last 10k rounds. There isn't much to break.
  2. My DPP came back from Leupold. Total turnaround time, including shipping, was 25 days. The invoice says "replaced bad circuit board". The new circuit board looks exactly like the one that failed. The central contact is still being held in place by the same sticker, so Leupold has no "fix". Sadly I'm witnessing another example of regression to the mean.
  3. So it looks like page 1 of this thread shows the failure of the new style sticker: And this new style sticker looks exactly like the one that I sent back to Leupold. If so, then the underlying problem still remains.
  4. Christian Sailer shoots Open, not Carry Optics. Nils shot Open at the 2018 Nationals, too. The well known problem with DPP (serial numbers ending in AF) happens primarily with slide-mounted red dots. The center contact shifts back at the moment the slide stops at the rearmost position. Frame-mounted red dots never experience as much deceleration.
  5. There isn't much difference. Median time to get to the next classification level is about the same in all divisions. Just pick a division that is popular. It's not much fun winning the Revolver or Limited 10 division at your local match if you're the only one there. I would avoid Open initially as the equipment is expensive, so this means Limited, Production, Carry Optics, or PCC. As far as classification goes, the new divisions that don't yet have their own high hit factors tend to be easier, but this is temporary. I think PCC high hit factors already went up, and CO will soon follow.
  6. There are about 4,000 people shooting Carry Optics. It's a rounding error compared to 10 million hunters. Now if a military or LEO customer complained that would get some attention. But apparently those either don't shoot enough to notice, or are getting different circuit boards.
  7. Judging by the pictures in that thread, the new board is like the old board, only the contact is rotated 45 degrees. That means the underlying problem remains, but redneck mitigation I came up will be less effective. Mine is still at Leupold, they estimate it'll take 18 days. Now I'm not sure if I want the return to have the new board.
  8. Wow that's a lot. I did not record temperature, but I did measure velocity in December and July, outdoors, and the difference was nowhere near that much. You're sure it's not the chrono?
  9. I switched from M&P9Pro to Tanfoglio Stock 2 (similar to CZ Shadow 2). I did not see a measurable difference in my scores. First shot and transitions are faster with M&P, splits are faster with Tanfoglio. Overall it's a wash. Maybe at GM level there is a meaningful difference, but I'm nowhere near that.
  10. Judging by the picture, the new circuit board (with "Leupold" written perpendicular to bore axis) has the center contact attached the same way. The only difference I can see is that it's rotated 45 degrees. If that's the case then how is it better than the old circuit board (with "Leoupold" written parallel to bore axis).
  11. Get a DA/SA gun like CZ Shadow 2 or Tanfoglio Stock 2 and shoot production. I have not heard of a single case where somebody shot himself in the foot with DA on the draw. Safety on before holstering, even though it's not required. It does not take any extra time to disengage the safety while you're bringing the gun up to eye level. Get a holster that prevents the gun from pointing inward, towards your leg. Shoot USPSA rather than Steel Challenge. On a 20 second stage the difference between 1 second draw and 1.5 second draw is not as important as on a three second Steel Challenge string.
  12. Breaking the impact with the elbow is dangerous. With enough energy and hard surface you can fracture not just the elbow but also the clavicle, and there is some pretty important stuff around the clavicle you don't want ruptured. Falling sideways on the shoulder can have similar result. There is a way to do kinda-sideways roll (abovementioned ukemi), but it's not easy and at the end you will still likely land on your mag pouches (ouch). My current solution is not to push so hard to avoid falling in the first place. I know it's not very competitive, but I don't see a better alternative.
  13. I spent a few years learning to fall safely when doing martial arts, both empty-handed and with wooden knife/sword. I really don't want to apply this knowledge at a USPSA match or in training. Not only because of the need to avoid sweeping and breaking 180, but also because doing it on the gravel sprinkled with spent brass and rolling over mag holders will be very unpleasant.
