Magazine block for dry fire practice

Magazine block device for firearm dry fire practice which allows a user to practice proper firearm handling skills without expending ammunition, including recocking and actuating the firearm slide without pressing the slide lock release. In an aspect, a magazine block device is provided having a bullet-shaped body, two upper ridges forming a longitudinal channel through which the firearm breach face loading tab may pass without dislodging the magazine block device, and an offset lower ridge. The lower ridge is configured to evenly force a magazine follower down a sufficient distance to prevent actuation of the firearm slide lock. This allows dry fire practice of pulling the slide. Several other features include ridges to assist a user to remove and load the block device in and out of a magazine, as well as a pocket to mechanically remove same.
