You have one of the new Combat Competition with the MatchLEM trigger and it only comes in black, your pistol is not a Custom Combat. Some people were calling the .40 version Custom Competition - thats not correct, all these color frame pistols in .45/.40 with the above features, were billed as "Custom Combat' by Heckler & Koch. The Custom Combat uses the standard factory USP trigger.Color frame only on the Combat Comp. .40? I don't think so seeing as I own a black one.
Also, don't forget the trigger is a Match trigger crossed with LEM. The first DA shot (when decocked) is light like LEM and then the pistol reverts to SA with more of a Match trigger feel with very little take up.
