Two guys that I know of at my club shoot G21's and do really good with them. But they have been shooting with them over 20 years each and are well used to the pistols and the loads they make. One of them is a M class shooter and he got it using the same Glock. He's running a vanek trigger, Arredondo pads and not sure what else but with the load he uses it shoots softer than my 35.
