Check. I felt exactly the same way when I bought my Gen 2 G19 (bought it new). Years and many thousands of rounds later it still works like a champ. I haven't detail cleaned it more than 4 or 5 times over the years and it's never once failed to work exactly as it should. I really like my G21SF too but my G19 is something special.
In part, this is why I was interested in getting a Glock. As long as it starts out reliable, it should continue to be that way with limited servicing. I shoot my Sig better and I don't think the Glock is as comfortable to shoot, but it's still a minute of man gun and one that's good to have in the stable...or so I thought, which is why I wanted one (and even got it as a Xmas present).
