Just got my M&P9 back from Smith this past weekend, sent it in for warranty work. They changed the extractor and the ejector (it had a crack in it when I bought it) I sent the gun in through my dealership and it took about 3 weeks to get it back, not bad considering Christmas and New Year's holidays in there. I took it out and fired 100 rounds throught it and only had one hiccup, again with WWB. All my handloads worked perfectly, so I am staying away from WWB for now. All well, just thought I'd give a report.
