I got DTU so far shot 200 rd no problems at all love this gun. Did you just get one? You having problems? Did you have a star stamp on the back of your manual?
Well, I just wanted to update my SN to DTU7***. I have found a DTU5*** with a blown extractor
Not sure I understand?
Well, I spoke S&W customer service today. He states that the SN's have nothing to do with the suspected known issues. He stated that the good vs broken mp22's that come back to them are very one sited. Meaning that there are very little that comeback for ftf,fte and extractor issues in comparison to how many they have sold and are good to go with no issues. But keep in mind less people will join a forum to report good things. They will normally join to report problems.
