This guide details the proper technique for safely loading the M1 Garand, specifically addressing the common 'Garand Thumb' phenomenon. It emphasizes maintaining downward pressure on the en-bloc clip during loading to prevent the bolt from slamming forward prematurely. Expert instruction from Garand Thumb highlights this as a key safety measure for new shooters.

This comprehensive review of the Russian Altyn helmet, presented by Garand Thumb, details its construction and ballistic performance. The helmet features a 3mm titanium shell with an aramid liner, rated for pistol and fragmentation threats. Testing reveals it stops 9mm and .44 Magnum rounds but fails against rifle calibers like 5.56x45mm and 7.62x39mm. Despite its robust construction for its intended role, its significant weight and lack of rifle protection are noted as drawbacks compared to modern alternatives.

Garand Thumb, a recognized subject matter expert in tactical equipment, critically assesses the effectiveness of ballistic face masks. The video details rigorous testing using realistic ballistic dummies and various firearms, from handguns to rifles, to measure projectile stopping power and backface deformation. The conclusion highlights significant risks associated with these masks, primarily due to severe deformation, suggesting they are often 'gimmicky' and less effective than traditional head protection.

This guide details the correct technique for loading the M1 Garand rifle, specifically addressing how to avoid 'Garand Thumb.' It emphasizes the 'bladed hand' method, a crucial technique for safe and efficient loading demonstrated by the speaker. Proper execution involves a swift, decisive motion to seat the en-bloc clip while protecting the thumb from the forward-moving bolt.
