The OP asked about QA1. Some of you are talking about QA1 and CAP as if they are one and the same. I don't think that's fair to QA1. I was over there at a plant tour when they were developing the QA1 K frame. I don't know whether they bought CAPs design or not, but whatever they did, they put their own design engineers on it. Judge it based on QA1 reveiws, not CAP reveiws.
