I need to walk back some of my excitement hailing the 50th Anniversary Design an Appleseed Liberty Training Rifle. As much as I'd love to adopt it as such; it isn't. From the video below it appears this rifle will only be made in 2014 which leaves the door open for the Appleseed Project to work with Ruger in creating a real LTR; like Marlin has.
Ernest Langdon of Langdon Tactical has put out a short three-part series on shooting the double-single action pistol. It also appears that he is using a Wilson Combat Custom Beretta 92 in this particular video; notice the G (decocker only) Conversion.
