Hi there just bought a Glock 20 and first thing i noticed was that with normal factory 10mm rnds the brass doesn't eject far, but no other problems. Then I tried Buffalo Bore 220 hardcast and the slide came back and caught the brass every time. I have a 24 lb recoil spring in the mail. Any suggestions to get that brass to throw better ?
