Browning HI-Power Pistols
Bob Dunlap is a renowned expert on all of John M. Brownings pistols. He understands the design, function, and repair of the firearms of the unchallenged genius of modern firearms design better than anyone else alive today. We use a cut-away gun to let you actually see how the pistol and all of its components operate. If you want the quick course on how to get Brownings final pistol design 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:

- Addition of the magazine safety
- Addition of the Modern staggered column hi-cap magazine
- Like so many of Brownings designs, it has been manufactured by many countries, has been the service weapon of many more, and is still in production today
- Production of the gun has been very long lived, like so many Browning designs, as the gun is extremely durable and reliable
