Another thing I will say regarding the Mk23 OHG was that is was produced, tested and manufactured with undue influence from the Navy/SEAL Teams.
It's nicknames are the "Boat Anchor" "Horse that a special committee made into a camel" and "Divot Fixer" ( GolF anology)
It's merits ? 110% reliable in any condition you can imagine. Accurate ? One of the most if not the most accurate "Out of the box" pistols you'll ever find.
I used to moderate a forum called
www.Mk23.com There where several SEALs that either loved the pistol and it's components or flat out hated it. There didn't seem to be any "in between" affection for the weapon system.
I owned one for years, with two different suppressors and I finally traded it for a high end 1911.
Colt and Hk submitted their designs for RFP and Colt produced a very unimaginitive 1911 with a longer grip to accomdate 12 rounds and a seperate decoking lever. It was the worst thing I've ever seen from Colt.
