So this is one of those posts where the OP just wants to gripe, complain and blow off steam but is not really looking for a solution or dissenting opinions???
Ok. First off, I check barrel/cylinder gap (eyeballs, don't own feeler gauges), fit & finish, timing, etc., before I commit to buy any revolver, new or used. I figure after buying over 80 revolvers I should know what I'm looking at by now. Secondly, I don't understand all the crap that people measure to look for problems in a new gun before they even shoot the damned thing. Yes sir, how it shoots is really all that matters. I NEVER go looking for problems until there's a symptom, seems ass-backwards to me. The symptoms only show up in shooting. If you're not testing your revolvers for accuracy, how do you determine whether or not they're worth a crap? Third, your "problem" doesn't sound like a problem at all. Are you just looking for something to complain about? It would be an issue if it were a $3000 Freedom Arms or a $5000 custom but for a production Ruger or S&W, it sounds like you're just looking for something to complain about. Again, as folks have kindly suggested above, to which you have rudely responded, all that matters is how it shoots.
