The only caution I would throw you guys' way is this: As a former gunsmith, most of the damage I saw to firearms was self-inflicted by their owners. Almost all, in fact. Reassembled wrong and forced together, screws buggered beyond recognition, parts "left over", and wood cracked from overtightening. Those are the probably the common ones, and sometimes (and this used to drive me crazy) some genius would perform one of these miracles on a brand new gun that certainly needed nothing beyond field stripping. Yes, if you're handy and patient and have the right tools, disassembly is fine. However, most modern manufacturers recommend field strip only, not complete disassembly...why? Because they see the same issues I saw when guns are sent in for "warranty work", LOL. The fact is, there are many people who cannot drive a screw without buggering the hell out of it, or remove a pin without scaring the receiver.
If you're handy, go ahead. If you know nothing about tools and things mechanical, think twice.
