I've owned lots of hand guns including several glocks. Guess the odds have caught up with me. Just bought a G21sf, have had it out to the range twice and about 80% of the spent brass hits me in the face/head/shoulders. The gun is second hand but looked as new/never fired when I bought it. I looked at how the ejector makes contact with the back of the casing and it hits at about the 8:00 to 9:00 position. You'd think that would fling it nearly straight to the right...not so. I even have some of it wind up behind me a slightly to my LEFT. Please, any help???
