AGI Armorer’s Course for Beretta PX4 Storm Pistol

Bob Dunlap is a renowned expert on many firearms, including Beretta pistols, rifles and shotguns. He is a big fan of Beretta, both for their history, design and execution of their products.

For those of you looking for practical instruction in how to get your Px4 pistol completely apart, clean, troubleshoot, make common repairs, and get your gun back together  and operating properly with none of those pesky and embarrassing leftover parts, you have come to the right place. Bob uses a cut away gun so that you can actually see how the internal parts function and their relationship to one another. This will help you to understand the design and function of these guns.

If you want the long course, on the design, function and extensive repair of this gun and firearms in general, look into our basic 108 hour Professional Gunsmith course.
