Well, no one responded, so for posterity, just in case anyone IS interested: The course was excellent. I had already had some relatively minimal training on-the-job when I was a small arms repairman in the military, but the 1911 was almost completely out of our inventory, so I never got to play with them much in any official capacity. Anyway, I went to the two-day course at Gunsite in AZ. Primary instructor was Dean Caputo and the assistant instructor was Mike Winter. Both of them were extremely helpful and knowledgeable.
Day #1 was a brief history of the 1911, and genius John M. Browning. Following that was issue of SS government model .45s (Series 80) and disassembly to field strip, followed by detail strip and inspection of parts and function checks of operation and safety functions. Throughout the class there were applicable and informative stories of issues encountered with the platform from the perspective of LE armorers at VERY large departments that still field 1911s as an officer carry option.
Day #2 was almost all disassembly to detailed, complete strip and practice with tuning extractors, fitting thumb safeties and grip safeties, etc. At the end of day, we were evaluated on disassembly to a complete strip, reassembly, function checks of all of the 1911s safety features, and a written test. I learned a lot and have zero regrets. The facilities at Gunsite were fantastic and I definitely recommend the course to anyone that wants a more in-depth understanding of the 1911, how it was designed and intended to operate, troubleshooting, fitting of parts, etc.
