I still haven't seen anything other than speculation that the factory spring isn't adequate. It would be interesting to find real life data on what the spring absorbs and what levels of energy are detrimental to the frame. All the speculation on distance brass is thrown have nothing to do with the construction of the gun or its lifespan. In fact, I haven't seen evidence of issues caused by the use of the factory spring either, which is odd if it really is a problem. PistolPete is thousands of rounds into the factory RSA w/ no issues, which suggests that the factory weight is fine.
