Well, Im not sure where to begin.
Yes, there is an armorers course and I have been to it. It would be slightly more difficult than the Glock course, IF it was taught correctly and completely, the way it should have been. But the instructor we had, had VERY LITTLE KNOWLEDGE of the MP, design principles, changes that were made, ideas behind what SW did, how the gun operates, etc.
A pin punch set, small hammer and maybe small screwdriver should suffice. I dont know b/c the instructor did not bring or have anything for us, except a single small slave pin, that we really didnt need and could have used a small screwdriver to do the same job.
We were not shown, taught/instructed, or allowed to take out the extractor or sear assembly. We had to look at pictures and were verbally told what would happen.
Very poor course for dept armorers and lack of knowledge on instructor's behalf. It was not harder than the Glock course b/c we only took the gun apart one time, together as a class. Thats it. Not multiple times of disassembly/assembly, or practical disassembly/assembly or written test. Also did not have a cut out of an MP or even showed how the parts works together or how the sear assembly works. Ive learned more here than in the armorers course.
