H&K USP versions ?

[10X]

I see some ads listing the full size guns as Version 1 or Version 3 etc.
What are the differences?

there are different variants on the type of trigger (DA/SA vs the "LEM" which is a consistent DA). I think there's also a option for +/- decocker.

edit: here's the "definitive" breakdown from HK global website. couldn't get it to cut and paste the info, go to the bottom of the page:

from the HK website, doesn't list the "name" for each variant ( http://www.hecklerkoch-usa.com/usp_compact_features.html )
Modular design with customer-specific design possibilities, for example:
- SA/DA Variant Double Action/Single Action with safety lever for safety and de-cocking function, arranged on the right or left side
- SA/DA Variant Double Action/Single Action with safety lever, arranged on the right or left side
- SA/DA Variant Double Action/Single Action with safety lever only for de-cocking function, arranged on the right or left side
- Variant DA Double Action with safety lever for safety function, arranged on the right or left side, without de-cocking lever

and here's a link w/ the differences b/w Variants 2 and 3 on the P2000:

The variants differ by model. A USP V1 is not the same as a P2000 V1. The HKusa web site is useful as is this one...
