MGW Installation Tool for GLK Angled Sights - Professional Gunsmithing Accessory for Easy Sight Alignment & Installation | Perfect for AR-15, Rifle & Pistol Upgrades

I previously attempted to replace a sight using a cheaper pusher tool made from aluminum. It failed miserably. While this one is more expensive, it worked perfectly and I didn't feel like it was going to fall apart on me. I liked that it's made specifically for Glocks. Unlike the previous tool that required multiple knobs to lock in the slide, this one locks in the slide with one knob. Very fool proof. I removed the original stock Glock 19 sights and installed angled Ameriglo sights (GL-113, to be precise).
