Firearms are mechanical devices that will wear out over time with use. Some parts are replaceable, some are not. I don't shoot near as much as some on here, and I've replaced a worn cylinder stop and shimmed a cylinder to reduce end shake. It's part of the cost of ownership. In 250 years, people just might complain that they have to replace the dilithium crystals in their Q-36 Space Modulator.

Everything is a tradeoff. Smaller size means easier to carry and better ergonomics for some. The downsides have been well elucidated in this thread and others. I don't chase magnum K-frames too hard because I want heirloom shooters. IMO they were terrific duty weapons that were never intended to be shot a lot for decades. But there are a lot of fine firearms like that.
