I just purchased the M&P Shield 45 last week and took it to the range today. I fired 200 rounds and the gun performed perfectly. Got home and disassembled it for cleaning. When I took the guide rod out the main spring popped right off. I called S&W and the tech just asked for my name and address and told me he would put one in the mail for me today. So, I was happy with the response from S&W but really disappointed in the quality of the RSA. I did asked the tech if this was a common problem and he tpld me its a very infrequent problem. After reading the forum it seems that it is a bit more frequent than what they are saying. If the replacement RSA has not been redesigned I'm concerned this may be a recurring problem. For those folks that have received replacements, have you run into the same problem with the replacements failing? Anyone know of an after market replacement that foesn't fall apart?
Other than that, it was a pleasure to shoot.
