Oops Sorry Man
...but there're many choices around so you can explore other brands from now on (Creation / Nova / PGC etc)...
What I Don't Like About Shooter's Design:
* Rough Finish (I got a KSC USP .45 fitted with SD's silver slide/barrel set: very quickly the top of the chamber heavily scratched and the rough-surface slide attracts stain)
* Incorrect Details: Often SD got wrong fonts for the markings (worst offender the XDM slide - both the words & logo dead wrong
)...also XDM supposed to go with black barrel even for silver slide version but SD become a smart-ass by making the barrel in silver as well...
From your pic I can see the black paint on your MK23 peeled off instead of wearing out...aluminium parts supposed to be anodised instead of bake painting or other ways that will lead to peel off...
