Blue Training Guns By Rings Glock 21 Gen 4 – FSG21G4

Realistic, Safe Training for Serious Professionals

Ring’s Manufacturing Inc. has built its reputation by providing safe, lifelike training tools for law enforcement, military, and security professionals since the early 1990s. The Blue Training Guns Glock 21 Gen 4 (FSG21G4) continues that mission. Molded directly from a real Glock 21 Gen 4, this non-firing replica matches the exact size, shape, and dimensions of the real firearm, giving you a true-to-life training experience without the danger.

Made from impact-resistant polyurethane, this training weapon is designed to take abuse without bending or flexing. Whether you’re in a classroom, on the mat, or running drills in the field, this Blue Gun provides the handling, balance, and durability needed for confident training.

Built to Train Like You Fight

This model is available in weighted and non-weighted versions. The weighted version simulates the feel of a fully loaded Glock 21 Gen 4, giving users realistic feedback during retention, holster draws, and close-quarters scenarios. It's a perfect solution for those who need gear that mimics live conditions without the associated risks.

Available in Law Enforcement Blue, orange, yellow, green, or gray, the solid color clearly identifies it as a training tool. Black is not available for Glock. This ensures there's no confusion during instruction, role-play, or scenario-based exercises. Better still, because it’s molded from a real firearm, it supports real accessories, including your favorite weapon lights, sights, grip sleeves, and more, so you can practice exactly as you operate.

Trusted by Those Who Serve
