My G21 Gen.3 with the factory (plastic non-adjustable) Sights hits approx. 3 1/2 inches high at 15 yards and even higher at 25 yards when shooting the 45 Super (it is approx. 1 1/2 inches high with 45 auto). I am considering adjustable sights but they are so darned tall, so am considering going with fixed sights and a taller front. So what sights or sight combination are you using and if fixed do they hit to point of Aim? thanks, Jerry Wanna kill these ads? We can help!
