USP ANATOMY

[Rocambole]

Hey :)

I need to know some detailed anatomy about the USP Compact compared to the fullsize USP.

Where is the 8,5 mm. height difference in the 9/40 compact from the fullsize, taken from? Are the sights lower on the compact? Is the slide the same dimensions (width and height) as the fullsize except for the obvious shortening, that is...

And is the safety lever the only thing accounting for the 4mm. loss in width?

Is the grip any differently sized except for the height loss? And how tall is the overall height with a match/tactical magazine floor plate on the 9/40?

Is the .357 SIG the exact same size as the 9/40? Are 9mm/40/357 magazines interchangeable on the compact? Are they steel or polymer?

Does anyone have a picture of the "flat compression spring contained in the captive recoil spring assembly by a polymer bushing" on the compact?


I see HK talking about decrease in trigger reach and grip circumference... and I am thinking... oh no! That will be way too small for me, and I will have to get the .45 just to be able to grip it :(
Did HK just mess up with their english and mean the height and overall width, or are they serious?



Thanks! :660:
