Reduced muzzle flip but....... - Align Tactical Glock Thumb Rest Trigger Pin

This rating is based on three shooters' opinions after installing the part and shooting the weapon (Glock 19). The installation was easy. Push out the original pin and put in the new part. Perfect fit and sturdy. For disassembly, you have to push out the part about a 1/4 inch, rotate it in order use the slide lock but not too bad. We took turns shooting the weapon from low ready to close contact positions, two hand grip. We all agree that you cannot press down too hard on the part, it causes the gun to dip but with the right amount of force, it helps with muzzle flip. We all reported during rapid fire, the thumb would occasionally slip off. Our double tap accuracy improved from the low ready position but a little awkward getting that thumb on the rest from the draw. One very important thing to know, it will NOT fit all holsters. Overall, YMMV. ( I will test it on my Glock 29 SF 10mm in the future)
