The M1898 Rast & Gasser revolver was the last iteration of a series of revolvers, and was a standard Austro-Hungarian sidearm during WWI (despite the adoption of the Steyr M1912 selfloader). The M1898 an often underappreciated handgun, with a number of useful features and a very high standard of manufacturing. These features include use of the Abadie system to disconnect the hammer form the trigger when the loading gate is open, to allow much faster reloading, and a hinged sideplate for easy and complete access to the working parts. In addition, it has an 8-round cylinder, equal (or greater!) in capacity to any semiauto pistol in service during WWI and for some time thereafter.
Thanks to Larry for loaning my this example for the video!
