The SST add on is only available to 455s over a certain S/N. Those were started to be produced in 2012, IIRC.AFAIK the main difference is that the 453 have the set trigger, and the 455 have the interchangeable barrel system. Other than that they're just sequential generations. Also, you can now get the set triggers for the 455's as well, if that matters.

That's correct. I checked mine when I read about it and I'm good to go, but I didn't know if I cared. After your shining endorsement of the SST though, I think my wallet may get a bit lighter. Thanks!?![]()
