✔ CUSTOM RELOADER: This is NOT a universal loader. We offer over 200 different magazine compatibilities. Please verify CALIBER and MAGAZINE compatibility in the dropdown menu. Each speed loader is designed to provide marksmen with the best comfort and utility for their guns. ✔ PROTECT YOUR FINGERS: MakerShot speed loaders allow you to drop rounds into each magazine without having to manually press each round with your thumbs. Easy load assist will prevent sore fingers at the range. Great speed, ergonomics, and durability decreases load time so you can get back to firing.
