First and formost I have to say this heckler and kock's mk23 also
known as the SOCOM tactical pistol, is one of the very best pistols
every made and it has been proven to be by many tests of the US
miltiary.

The tests which had to be successfully passed included the following: 

•  30,000-round endurance firing test with +P ammunition 
•   Tests at extreme temperatures +73*C/-50*C.  
•   96-h saline mist test  
•   Sand, dust, sludge test  
•   96-h surf test  
•   Harshest drop test  
•   Maximum accuracy and precision 
 

Secondly in a world of cheap ripoffs and inmations HK took the time to make the very best.
