Hi all,

I'm looking at pre-owned USP45's. Are there any significant changes to be aware of in the date code series?
Significant or moderately significant changes in design?

Thanks!

Bought it! paid for an absolutely pristine USP45. It appears to have never been out of the case except for an initial oiling. I'm tickled.
