Hello fellow Glock enthusiasts! Would appreciate some advice from someone familiar with my current setup. I recently purchased a G20 and added an Alpha Wolf 6.61", fluted and threaded extended barrel. My goal was(is) to increase accuracy and muzzle velocity. I plan to shoot some hot Underwood ammo and heard that a stiffer recoil spring is needed. I'd also like to install a compensator/muzzle-brake. My question is this: will the stiffer recoil spring be needed if a recoil-reducing muzzle brake is installed? Does anyone have any experience with a G20/extended barrel/muzzle brake combination?
