Fascinating! In 50 years of using guns, I've never had this question come up. I am able to detail strip every gun I own - Except the old Browning shotguns which almost never break, require precision screwdrivers to open, and are too valuable to screw around with - anyway.
Because I'm the only person I know who, ever, detail strips a revolver I suspect that your question refers, strictly, to semi-automatic pistols. (Revolvers rarely need to be detail stripped.)
After detail stripping a carry pistol, I'll function test it and, maybe, drop the hammer a few times. Generally speaking if the pistol goes back together without any problems, then, it's good-to-go. If you do something wrong when re:assembling a gun you usually discover it immediately because most mistakes will have a negative effect on the rest of what you're trying to put together. If you're not mechanically inclined it might put your mind at ease to use either, 'Gun Scrubber' or, 'Dunk-It' pistol cleaning solutions.
In my experience problems with carry pistols usually come from the ammunition - not the re:assembled pistol, itself. (PS: Anyway, you should always carry a backup gun - right!)
