The Mk 23 is too fucking big to be useful.
The Mk23 is large,as it was designed to be shot with big, bulky gloves. I don't know if you have ever shot one, but they extremely accurate. And I'm a Glock fan!!
The USP is also a nice pistol, and should be given high consideration.
Puller cracked his knuckles, loaded up his Colt 1911, and landed at the head of the 1st Marines at Inchon in September of 1950. At the Battle of Choisin Reservoir, Puller and his men found themselves holed up in the town of Koto-ri, completely surrounded by ten full Divisions of Chinese Infantry hell-bent on killing every American they could find and then re-animating the dead bodies to fight as their undead army of the night. Heavily outnumbered, and fighting in ball-freezing sub-zero temperatures, Puller’s troops broke the enemy lines, smashed through seven enemy divisions, and then stayed behind as a rear guard, bearing the brunt of the Chinese onslaught so that the rest of the Marines could complete their retreat (Puller refused to refer to it as a retreat, however, he preferred to call it, "attacking in a different direction").
"All right, they're on our left, they're on our right,
they're in front of us, they're behind us.
They can't get away this time."
- Davie Crockett was really good with his flintlock, but I'd bet on any 18 year old PFC with an M4 against him.If a 1911 was what he used, then let the rest of the Marines use it too. It is not the weapon, it is the person behind the weapon.
