I think he meant the 12.7mm Pistol.
Probably. But the 12.7 pistol really doesn't come across as being the King of Magnum Hand Cannons, though. It just goes 'bang' and shoots a bullet. A powerful bullet, but you don't get the feeling that the gun is anything special. And it looks like puke, to be honest. Both of the 12.7mm weapons are so downright fugly that my chars are embarrassed to be seen with them. Now a true .50 caliber magnum pistol, like the Desert Eagle, should kick like a mule (visualize a 1-handed AMR recoil... lol) make a really loud bang, and drop things like it was the Ranger Sequoia's big daddy. The recoil alone and limited shots would make it poor as a rapid-fire street-sweeper weapon, of course- but as a situational weapon that could blow most opponents across the room with one shot in the brisket... who cares? Now that, I would like to see.....
Clint stood erect at the entrance to the Quarry, mildly displeased with himself for having only wounded the massive Alpha Deathclaw at long range, with his saddlegun. As the onrushing beast rocked the canyon walls with its bellowed rage and came at him like a two-ton mountain of implacable clawed doom, he carefully relit his cigar before drawing out the Desert Eagle from its holster. Squinting intently, he carefully leveled the heavy weapon's front sight on the middle of the deathclaw's chest as it rapidly closed the distance between them. Taking a deep breath, he uttered these immortal words... "Come on, b****, make my day!"
/cut to Chet's general store in Goodsprings: Clint: "Whaddaya mean, only 20 caps for these perfect alpha claws?!? Why you cheap little wuss, I oughta just take you along as bait, on my next hunt... .."
