    Open gun lengths

    And the new gun has the right colors: purple and gold!!!
  2. Stress risers at the corner of the cuts. Cuts not properly de-burred and sharp edges softened.
  3. Extreme Engineering, hands down. I have used them in all of my builds since 1995. Cylinder and Slide as well as Brazo's, and many others, are EE parts.

    Ejector Rejector

    Looking at the extractor hook from the center line of the pistol, does the hook have a radius at the bottom, front to back? If so, that will allow the empty to tip up and leave the pistol rising instead of moving out sideways. I am not familiar with Tanfoglio's but the basic ejector/extractor principles should be the same.

    Ejector Rejector

    You want the ejector shaped so that the top of the ejector hits the case before the bottom. The picture of the ejector in this thread clearly shows the bottom of the ejector forward of the top. That will drive the case up and not have it come out flat, to the right. Also, look at the shape of the extractor hook. A radius on the bottom will direct the case to flip up rather than to drive it out at 2:30 - 3:00 o'clock.
  6. You will need the back of the comp or the front of the slide cut at an approx. 1 deg. angle. You don't want the slide to ever touch the comp when cycling. I set up my builds with about .005 clearance. The hood will wear over time and the extra clearance lets you go longer before having to reset the loose comp (from the slide hitting it) and reset the clearance. The 1 deg. has nothing to do with the bushing but everything to do with the lockup angle when the barrel is in battery.
  7. From your pictures it appears to me that your frame has been cut through what would have been the vertical impact surface all the way to the mag well. If that's the case you'll have to start with a new frame and go from there.
  8. jwhittin, it's not the barrel. It's the frame lug at the front of the trigger guard. But thanks for the reply!
  9. I have a customer with a custom STI pistol, not a factory gun, that has broken the front lug off, I think due to an improperly fit Cheely grip. Does anyone know of or can recommend a shop that can correctly repair the frame? Thanks for your help!
  10. SAS serial numbers were for Shirley Ann Skinner, wife of Dave Skinner, when they owned STI. Probably late '90's to early 2000's.
  11. The first STI slide I bought was in 1995 and it had the map of Texas on it. They may have gone back to it with all of the changes they have made in the last 9 months or so.
