I have just passed the 3 million mark on my Sig 229. When I picked the gun up in the early 90's, I thought, here is a nice little gun--but an aluminum frame? So I began my quest to tourture test it. First I dropped the gun in a vat of sulfuric acid--no M/Fs. Next, I had the gun dropped from a helicopter hovering over a live volcano at Mount Tiki-Tiki--no M/Fs. Next, I had the gun frozen in neon at 40 degrees below absolute zero. Not only did it function--it was cryro accurized! Next, I had the gun dragged behind a land speed record holding rocket car at the salt flats--no malfunctions. At this point, the finish began showing a little wear. I decided to have the gun black -T'd. To test this, I had the gun bead-blasted with industrial diamonds. After going through five Bosch 66xxx66 mega blasters I decided black -T was all right. Then I fired 3 million triple charged extra-thinwalled 40 S&W rounds through the gun in two afternoons--no malfunctions.
Unfortunately, the problem with the finish coming off really keeps me from recomending the 229.
Next time I'll tell you about my REALLY TOUGH long-term G17!
