Everything old becomes new again so why not bring back our favorite custom guns.

Revolvers have always been our true love to build and in our opinion, classic single-action revolvers are the best.  Carol and Kerry have hunted around to world with big caliber revolvers built by MG Arms and we are proud and excited to bring two of our revolvers back on a limited production run.


First, the DragonFly was designed to be the lightest big caliber, single-action revolver on the market.  Weighing just over 1 pound in .38 Special or .44 Special makes this a great and fun revolver to carry.  [Learn more] 

Second, the DragonSlayer is a handgun hunters dream.  Easy, light, and small enough to actually carry.  Made in the biggest and most powerful calibers in the handgun world. Big enough to kill the largest of game animals and small enough that it doesn’t need a bipod for support.  [Learn more]
