My brothers favorite words. "follow the manufactures instructions"
I've been following the instructions in the S&W manual, it's on their web site.
I just field strip down to the frame, slide, recoil spring and barrel.
I use Froglube CLP. Plus a 9mm bore snake, Allen Co. Patches, an Outers brass pistol rod, Dixie cup, old tooth brush and old wash cloths.
While I agree that it would be unusual to have to do more than a field strip, I think saying it's a bad idea to do more without the armorers course is a little over the top.... it is actually a bad idea for a person who has not been through the armorer's training, to attempt to disassemble any further than a basic field strip as shown in the manual.
