This is Colonels Smoking Gun, fondly known as Gunner. Gunner was part of the NRHA (National Reining Horse Association) and was a $5 million dollar Quarter Horse sire. Sadly, on July 8th, Gunner was euthanized. He was diagnosed with laminitis. Colonels Smoking Gun was a beautiful sire and an amazing reining horse at the top of his game. Thoughts and prayers to Gunner's family.
