hello all, I haven't posted here in awhile, but wanted to add my two cents worth to jimmyD based on my experience with my R9s. First, I agree with the above comments cautioning against taking online, anecdotal stories as reliable evidence of a product's quality, reliability, etc. With that said, my experience with my particular R9s has been totally flawless, and I have approx. 650 rounds through it. I have received two phone calls from Eric Rohrbaugh concerning small orders I placed for extra magazines, grip screws, etc. Eric called not only to confirm or advise regarding my orders, but seemed more interested in hearing if I was happy with gun, and whether it was working properly. I have NEVER had that kind of service from any other gun manufacturer. I cannot imagine anyone feeling Rohrbaugh does not offer excellent service above and beyond that normally expected by the customer. I dont know how much stock you want to put in one more customer's expeerience, but there is mine for what its worth. As to questions regarding tolerances, I am no engineer, or expert of any kind on that subject, but it seems to me that tighter tolerances would always be preferable as long as gun remains 100% reliable. I know mine is so I am happy. Anyone who owns one that is not relaible may have legitimate question regarding tolerances, but I would assume everyone prefers tighter tolerances if all other things, i.e. reliability, remain equal. If there is serious problem with R9s reliability, then maybe there is a legitimate question there. I am just not aware of any serious, widespread problem and do not believe there is any reason to suspect one exists. The vast majority of R9s owners appear to be totally happy as far as I can tell.
