Today I attended the Armorer's Course, and I have to tell you it was the single best day of training I've EVER attended on any subject. The instructor, Dennis Tueller, was experienced, prepared, outgoing, confident, and professional. He has a great delivery style, and was able to keep things relaxed while he went through a lot of information, supported by an excellent computer presentation (PowerPoint, I think) that covered all of the material. The class ran from 8AM to a bit after 5PM, with a half hour for lunch. After a little morning presentation on background material, we spent probably 7 full hours working on the guns (G22s in our class), with every student (about 40 of us) having his/her own gun to work on. We went through complete function and safety testing, field strip and detail strip, and had some time for problem diagnosis. The time just flew by, it was that interesting and absorbing. Dennis and the local Glock LE District Manager, Dave Mallery, were able to answer every question in depth. To cap it off, we all got a current Armorer's Manual and addendum. I'm really glad I was able to get the training, and encourage you to do the same. You'll come away with knowledge you can use immediately with your Glocks, and you'll be able to help your friends with them as well. It's WELL worth the money and the time invested.
