If you own or work on any of these guns, then you need the information contained on these videos! Only AGI\'s Technical Manuals and Armorer\'s Courses instruct you in every aspect of maintenance and repair of your firearms. On these videos Master Gunsmith and Senior Instructor Robert \"Bob\" Dunlap teaches you complete disassembly and assembly (not just field stripping), parts identification, proper cleaning and lubrication. Bob also covers step-by-step instruction in design, function and repair, including: locking systems, feeding systems, sears, triggers, and safeties. AGI Armorer\'s Courses also include easy repairs for common problems and a FREE printable schematic when purchased in DVD format.

The American Gunsmithing Institute\'s instructors are all Certified Master Gunsmiths. At AGI, we adhere to the belief that you must fully understand how a firearm is designed to work before you can make any attempt to clean or repair it. AGI instructional videos provide you with this knowledge. Bob uses a custom cut away gun to enable you, in the usual AGI fashion, actually see how the parts you can’t normally see operate inside the gun.

If you want the “quick” course on how to get the Walther PPK/S and FEG PA63 pistols 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:

• Bob gives us the Post-WWII history of Walther. From the German company’s humble beginning, with some tooling and a few firearms diagrams, to the success of their product line of today, Walther continues to manufacture superb quality firearms
• Many guns were manufactured in France, even though their markings stated that they were made in Germany
• We are shown a rare Model 1001 pistol, chambered for the .32 ACP cartridge, which has East German proof marks on it. The jump from the ramp to the barrel is designed correctly, unlike the version made in France. The ramp was not manufactured correctly again until Interarms began to manufacture the pistol under license from Walther in the United States many years later
• Many countries have copied all or part of the well thought out Walther design
• Special Guest instructor, John Bush, fills us in on Walther’s early history and shows us a variety of Pre-WWI/WWII models and designs

• After WWII, Walther licensed their pistol designs to Switzerland and France as a way to make money in West Germany, as they could not manufacture firearms themselves at that time
• John shows us many different Post-WWII models of Walther pistols and shares some interesting historical facts
• We are shown some special accessories for the Walther pistols (4mm center primed conversion cartridges and special barrel for shooting indoors, etc)

• Through the use of a FEG PA63 cutaway pistol, we are shown the design and function of this unique pistol
• The differences and similarities between the FEG and the Walther are shown and explained throughout this section of the course
• The pistol is a straight blowback operated gun (no locking system or delay). This type of operation is thoroughly explained and demonstrated
• The extractor’s actual function and the ejection process in this type of firearm is explained
• The loaded chamber indicator is shown and demonstrated

• The decocking system is shown and demonstrated
• The functions of the hammer, hammer strut and main spring are shown and demonstrated (power adding and power robbing strokes are explained)
• The trigger bar and disconnector are shown and demonstrated
• The magazine and magazine catch are shown and explained

• Magazine disassembly is shown and demonstrated
• Slide disassembly is demonstrated (firing pin, extractor, plungers and spring, loaded chamber indicator). The unique movement of the trigger guard is shown
• Lower frame disassembly is shown and demonstrated (recoil spring, slide stop, hammer and main spring and plug, hammer strut, sear trip lever, hammer blocking safety, trigger pin, trigger guard, trigger, magazine catch, barrel)
• The feed ramp is shown and its function is explained. A diagram is shown to illustrate the proper dimensions of the ramp’s relation to the barrel is explained
