Thinking of getting a G30SF, or maybe even a G21, but they seem huge to me. I shot my brother's G21SF and I actually liked it. I own Glock 26, 19, and 17. Also a couple of G27's. Only .45's I own are 1911's, and I love them but they are too damn heavy... Are the .45 Glocks as good as the 9mm's and .40's, reliability-wise?
