Ruger® Standard Auto .22 Pistols

Ruger® Standard Auto .22 Pistols


Product ID# 114DVD

Ruger® Standard Auto; Mark I, II, III, & 22/45™

Bob Dunlap is a renowned expert on most of todays and yesterdays important and obscure firearms. He has been a warranty station for most manufacturers, both large and small. He understands the design, function, and repair of firearms in general, and certainly, the gun that got Ruger® off on a successful footing, the Ruger® Standard Auto. We use a cut-away gun to let you actually see how the pistol and all of its components operate. This latest version of the course covers the new Mark II™I and the 22/45™ Mark II™I versions of the gun.

If you want the quick course on how to get the Worlds Most Popular .22 Pistol apart, back together, and operating as intended, then this course is for you (if you want the "long course," look into our basic 108 hour Professional Gunsmith Course.)

Among the items covered are:


  • Founded by Bill Ruger® and Alexander Sturm in a small rented machine shop in 1949, the Standard Auto was their first production firearm
  • Ruger®s innovative design had a stamped two-piece frame that was welded together and much cheaper to produce than a forged and machined frame.
  • The gun looked somewhat like the famous Luger pistol and Ruger®s name sounded like it
  • The gun was originally priced at ~ $30, a few cents cheaper than the High Standard Duramatic, the former champ of low priced, good quality .22s, and worked and felt better
  • Was and is a great value for the money, and is still the top seller of the .22 Semi Auto Pistols

  • Why the bullet is gone from the barrel before the bolt starts back, the idea of Mass vs. Gas

  • Pay particular attention to the magazine catch disassembly
  • You get a good look at how the various parts fit together and interact (particularly the springs) after they are removed from the gun and Bob explains things

Cleaning & Lubrication

  • After cleaning, dry with air gun, or in the oven on Warm ~185-200 degrees (metal parts ONLY)
