I have a Glock 20C. Oh it is a fun and enjoyable gun to shoot. Have shot a friend of mines regular Glock 20 as well as a Bren 10. The compensated barrel on mine is a pleasure to shoot. I won't tell you anything about the grip size, etc, as you seem to be familiar with that, and also, the last time I voiced my 2 cents on this subject, I started a tirade with an internet expert. Like I said, I love my 20C.
