Have no direct experience with the 40 caliber 410 model itself. I do have the 9mm 908S however. The 410, 410S (s=stainless), 908, 908S, 910, 910S are "value line" version of third generation S&W's. Lifetime warranty. I had to have the feed ramp polished on my 908S to get it to feed reliably. It was a little tight I guess (got it done for free....well, since he did it for free I bought another gun from him...so free is relative). Once polished (10 minutes or so) began feeding and shooting perfectly. Have not had the hint of a problem with it since. And from a rest, it is pin point accurate..and I do mean pin point (15 yards). Off hand I have a little trouble going a little high and right...but that is me because I am use to heavier weight hand guns. Overall, not only do I like it I am impressed with it. I have a lot of firearms and traded in and out of many others. Based on my 908S performance (after polish) I actually feel as though it is undervalued and underappreciated because it can match or exceed many much more expensive hand guns I have, have owned, and/or fired.
