  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.
  14. https://patriotdefense.com/patriot-defense-tanfoglio-cz75-base-pads-small-frame/ or this? Patriot Make them for both large frame and small frame magazines. Many polymer are small, but some large ... so you have to double check
  15. https://www.henningshop.com/Detail.aspx?PROD=1292071&CAT=10208 are we talking the same thing?
  16. don't know. have you contacted the companies that make them? Taylor Freelance and Henning come to mind. Both top notch makers.
  17. What hammer spring? By the way, 2nd strike ignition is a classic sign of primers being too high. Ideally, they should be 0.005" to 0.008" below flush. This is Vital with weak hammer springs. And verify oal is good and crimp is consistent. I test every round in a hundo.
  18. For me (a lowly A class slob), just taking more time to move the trigger helped tremendously. 15yd splits of 0.75 weak hand get me pretty reliably in the A zone, 0.5s splits are 50/50 A or close C. Rushing it even a little or losing focus on the trigger just kills the accuracy. This and more da dryfire too.
  19. File or dremel the "lip" below the groove that the mag slides into. Just did this for a buddy. he was limited to 20 before to be reliable, instantly went to 22. once the springs set, he will be 23 reloadable.
  20. Spend a (very) few dollars and buy a patriot defense firing pin return spring (robs less power from the hammer) AND a patriot defense firing pin. That will light off cci primers in otherwise untouched guns (that don't have other issues). Also, the EG Medium spring should be good for a full season (20k or better).
  21. Call up PD. There is a holster company across the way from them. They might be able to make one. or check your local holster companies to see if they will mold one around your gun. I'm pretty sure you will need a custom holster as that is not a popular combo.
  22. I have not. but, my "stock" of springs is 18 months old. I get a pile at once to reduce shipping costs.
  23. My son is left eye, right hand.he taught himself to shoot pistol left handed. A work around is Scotch tape on the left lens to force right eye. Just a small piece.
