One Shot.
One Chance.
Many Choices.

  If you relish the challenge of single-shot hunting or sport shooting, the Lone Eagle™ Pistol is the premier pistol of its kind. But with the Lone Eagle's™ component-based design, you're not restricted to one caliber. By simply switching barreled actions, you can change calibers in a second or two.
The First Step. Begin with the foundation of the Lone Eagle™ Pistol, an ambidextrous grip assembly. This streamlined stock is made of Hyloy 610, a rugged polymer. Suggested retail is $119.00.
The Second Step. Pick your caliber or calibers from our selection of interchangeable single-shot actions listed below left. (You must see your dealer to obtain the grip assembly and barreled actions.)
The Third Step. A grip and a barreled action make your Lone Eagle™ Pistol functionally complete, but you'll probably want to add mechanical sights, or optics and a scope base, to get the most out of the gun.

Trophy Club: The Art of the Hunt

Hunters who hunt with the Lone Eagle(tm) or other Magnum Research products are invited to join the Magnum Research Trophy Club. When you join, you will receive a certificate of membership and a free Trophy Club T-shirt. Just provide some basic written information and a photograph of yourself with the trophy and the pistol or rifle you used. Your name should be noted on the back of the photo, and the following information should be noted on a 3" x 5" index card:
  • Name
  • Address
  • Type of animal
  • Type and caliber of firearm (must be a Magnum Research product)
  • When and where the hunt took place
  • Other interesting details or circumstances

          Entries should meet the following guidelines: 
  1. Any game harvested in a fair chase is a "trophy."
  2. The photo should be tasteful. The hunter and the firearm should both appear in the photo with the trophy.
  3. The photo should be taken at or near the site of the hunt (not in the hunter's den with a mounted trophy).
Photos and facts may be used in Magnum Research's promotional materials. (Photos cannot be returned.)

Trophy Club photos and cards should be sent to:
