    Disco revisited

    . I went with red loctite.

    Pretravel screw (upper) on the CGW “old style” trigger. As it loosens, it moves forward, blocking DA reset.

    Yes. Or the most obvious thing, that I didn’t check...the pre-travel screw had loosened. Arrggh.

    Disco revisited

    I fit the CGW RR kit on my Shadow 2 along with some polishing of internals. Very happy with results. Initially, the disco needed fitting to achieve SA reset. The DA reset seemed fine. Happy with how that turned out. However, after 200-300 rounds, the DA suddenly stopped resetting. After checking everything over, it became apparent the disco needed further fitting. I removed material from the appropriate surface on the disco and now DA reset is great. My question is, why would the DA reset be good initially, but after shooting the pistol a bit, then require further disco fitting? Sent from my iPhone using Tapatalk

    Interesting. Will do. Thanks

    Shadow2 extraction issue

    Thanks for the advice. It’s a new pistol and I’ve cleaned the extractor between sessions. Still occurring.
  7. I have a Shadow 2 that frequently fails to extract (1-2/50). Next round jams, empty casing still in chamber, magazine removed, then the empty casing can be ejected normally by racking the slide. The brass looks ok, the rounds pass the barrel drop test. Minor load, PF 130 or so. I’ve increased the recoil spring weight to 12#, ejection is vigorous (8ft), tried polishing the face of the extractor where the lip of each brass round slides over it. Extractor “looks” ok under a magnifying glass. Any suggestions? I have a spare extractor (for SP01, should work I believe). Also a spare spring but unable to source a “heavy duty” extractor spring. Have never had this issue on a number of previous CZ pistols. Sent from my iPhone using Tapatalk
  8. This is an awesome thread, studied it carefully. However, I'm still not 100% clear on which surface of the disconnector from which material is to be removed for double action reset issues. In the pic below, the arrow points to the back of both the wing and the long leg of the disco, is that the area for material to be removed, or is it the "bottom" surface of the wing (I think it's been referred to as the "hook") which is facing us in the picture?
  9. Not really an issue for me in a competition gun. Sent from my iPhone using Tapatalk
  10. Just the one side is all that was needed. Yes, we tried a number of things to increase tension between the extractor and the case, with little success. It’s spring loaded, tried a stronger spring, also tried removing some material from the extractor to allow it to travel in a bit further, creating greater overlap over the lip of the casing. None of those really made a difference, but once we made that support shelf, it has been completely reliable. Sent from my iPad using Tapatalk
  11. I hope you can see the relief that was milled into the bottom of the bolt in the pics below. I had trouble seating mags and noticed bent feed lips as well. After creating this relief, full mags seat easily. Sent from my iPhone using Tapatalk
  12. Issues from the get go. Not frequently, maybe 3-4 fte per 100 rounds, but enough to make it unusable in a match. Yes, Gibbz Arms has been contacted. They were nice enough to send me a replacement extractor early on but said they weren’t having similar issues from others (after adding the fixed blank opposite the extractor, which my bolt already had). They offered to have a look, but I chose to work on it myself. I’ve sent them my mod with pics and a description, no reply. I truly hope you have no issues and your rifle remains trouble free!

  13. Yes, we added the support at 6 o'clock (which is present on the bolts from other high quality manufacturers, including QC10, JP, Wilson, etc). It is not straightforward but my friend who added the material is a skilled welder and his dad who did the milling has some serious skills as well! I'm lucky to have such friends. He used a TIG welder and added a little extra material, it was initially just a blob there. Then we milled it down to the final spec. We talked about how the heat might effect the bolt, decided to proceed and it hasn't seemed to have had any adverse effects. Time will tell. I've run it through two matches since the mod and it has run flawlessly. Its nice not to have all that debris blowing back in my face!
