I would avoid most aftermarket parts. Sometimes mags, sights, grips are ok, but internals worry me. Gun makers have design engineers, test engineers and manufacturing engineers. Aftermarket parts are often the idea of one person of limited knowledge and experience, but with a web page and an EBay store. A few are better than that, but most are not.
This may well be true in some areas but let's be careful not to assume that every gun leaves the factory as good as it can be, or that every mass-market design is as good as it can be. Cost control is a big part of it, and the happenstance of innovation is another. Also, "good" can be more or less subjective depending on what kind of upgrade/change we are talking about and what effect the individual shooter is looking for.
For instance, I brought up the aftermarket recoil systems that replace standard guide rods. The idea has been used in the relatively expensive Hk USP. Many people love it, especially in the snappier .40 S&W. However, not everyone likes the way it distributes the recoil impulse and I've heard that some competitive shooters prefer a more traditional system.
So why not make similar technology available in other guns for those who want it? The idea that it lowers stress on components, if true, should be objectively good. The way it changes the recoil impulse could be good for those who like the feel. The real concern would be any reliability issues versus the standard systems they are replacing, and how they subjectively weigh against benefits if there are any. That's why we read reviews and shoot the breeze in places like this.
