Based upon the information that I have: :biggrin:
Serial numbers
1. 4-digit (96-98)
2. 6-digit (99-11)
Slide Markings
1. Mark 23 (96/210X through 277X)
2. MARK 23 (96-11)
3. "Gold" HK wJS (in circle)(04-05)
4. "Heckler & Koch" on right slide (early 04- late 05)- there are blocks within that period that have no mark on right slide
5. "DE" (08-11)
Finishes
1. Maritime/high gloss (96-early 04)
2. HE/flat (mid-04 -11)
Cases
1. Camo cloth (96- early 04)
2. European (97-99)
- early (gold aluminum case/fake wood outer inserts/"HK" logo in red on front/foam inner inserts/2 keys)--- CCF imported @ 100
- later (brushed silver aluminum case/ black outer inserts/"HK" logo in red on front/foam inner inersts/2 keys)
3. Black cloth (mid-04- early 06)
4. Tan cloth (early 04- late 05)- 1 of 500 tan frame
5. Black plastic (mid-06- 11)
Lockout Device
1. None (96-98)
2. Incorporated (99-11)
From a collector's standpoint, the 96/KG with combination of "Mark 23", camo cloth case and no "lockout device" is most desireable. :wink:
From a shooter's standpoint, any model.
