  1. Great input guys. While, finding out an idea is "straight up stupid" (and i do admit that) is no fun, I'd rather look stupid for an idea, than for a bad stage. So thanks! Will put that into the bin where it belongs.
  2. Ok, I'm designing a stage where the RO stands next to a barrel with the competitor's unloaded gun. The competitor is 25-30 yards away in a start box with a flag. The idea is, since it's too far for audible signals, the RO will raise an arm to "ask" if the competitor is ready. The competitor will raise the flag to say "yes, I'm ready", the RO will then wait and drop the arm and start the timer. The competitor will run to the barrel, load the gun and commence shooting. Question.... is that allowable? And acceptable in the rules? 3.2.1 seems to say yes, but ... more opinions are better. Especially on how to equitably do it. The benefit is the Ro isn't run ragged (lol) and the squad can be close to allow faster pasting. Thanks
  3. Lets see... Lighter than factory...fails factory ... passes PD heavier than factory.... hmmm? I have 25,000 on a PD firing pin with no failures. the gun sets off everything tried with the 15.5 hammer spring and pd return spring. just my experience.
  4. i would increase the recoil spring, but I don't shoot 10mm, so that is "theoretical". the other springs don't need to be changed, but the hammer spring can "fine tune" the recoil force curve. However, in a DA/SA gun that can cause the DA pull to become extreme. Most don't want that trade off ! (I don't).
  5. I would suspect you used a bad email address or the isp had a glitch. They respond quickly.
  6. I also heard adaptor plate in a dove tail mount was the only option.
  7. Huh, learn something new everyday. that method is one I hadn't thought about, probably as I try to stay away from the sear engagement side of things. That is an area where experience and the correct tooling are important. Anyway, Thanks for bringing it up! One point, the Tanfo sears are only thinly surface hardened. removing the bottom material ... do you think it will let the sear wear faster?
  8. Www.gunparts.com. they used to have them
  9. You need the da trigger too. (But you probably knew that)
  10. I use 1/16" for the ambi safety and sae sizes for all other pins. Ones that are just slightly small. (obviously) I'm sure metric would be "best", but these work fine. Hot tip, replace the trigger pivot pin with the canick pin from CGW.
  11. This is IMPORTANT... Look at that red box. Look close. ONLY REMOVE material from the BOTTOM of the curve. NONE from the front of the point. Plan on assembling, testing, disassembling then removing a SMALL AMOUNT of material and repeating that process 10, 15, 20 times! You can take off more, but you can't take off less.
  12. It sounds like the notch in the slide is rounded over so the slide slips off the release too easily. Just a guess.
  13. from the henning link "Henning Tanfoglio 9mm 23+1 USPSA Magazine Extension with Follower Kit" The link was for tanfo mags.
