Come on, does anyone here really read gun manuals? Exploded parts diagram is specifically excluded. There's nothing to read!!! I could only wish a helpful manual would come with a gun. One that explains step by step how to detail strip every part in the firearm, with an explanation of any special tools needed, where to purchase them and prices for special tools.
Then there should be a specification section that outlines exactly what the gun is made of, i.e:
Total of 93 parts:
Frame: Investment Cast Stainless steel, 416R
Slide: Forged high-carbon steel
Trigger:.....
Sear:......
Springs:......
(complete with prices and ordering information)
And performance specs:
Muzzle velocity with xyz ammo.....
Accuracy specifications
Durability factor
Trigger lbs.
Trigger take-up and overtravel specs
Lubrication specs and details
Next, there should be a section for "common problems/parts that break" and details (with pictures) on how to fix/repair such problems.
And finally, a comprehensive of aftermarket goodies available for the particular gun.
That's what should be in the Manual.
