What guns did billy the kid use?

Answer 1

An 1873 Winchester Carbine, it was shorter and lighter than the rifle, and carried a dozen .44-.40-caliber, center-fired cartridges (the rifle carried 15) and a single-action Colt .45-caliber Peacemaker as well as the double-action Colt .41-caliber Thunderer (the Kid's preferred the latter). His favorite firearm was the 1873 Winchester Carbine.

Answer 2

We know with out a doubt he owned and used a Colt Model 1873 Army SA in 45 long (single action) and a Winchester Rifle Model 1873 44-40. Both of these weapons are in Billy's possession in the only known photo of him.

Billy has his Colt on his left side and is holding his Winchester (which was his weapon of choice). Due to the Colt being holstered on his left hip many people believed he was left handed. This how ever is an error. Any "gun guy" worth a lick of salt would have noticed the Winchester was backwards on close inspection. Back then when the photo was developed they had to reverse them because they were backwards. That was never done.

As for other guns many historians believe he had a Colt Thunderer, or Lightening and more then likely he owned my favorite revolver a S&W Schofield in 45 S&W, known know as 45 short. Even though the Colt and the Schofield are both chambered in a 45 caliber projectile the caseing is longer on the Colt which gives it a little more power but the Schofield can reload much, much, quicker. Especially while on hoarse back.
