..., but my favorite is the CZ compact clone I have.....the C100 Tri Star. It seems to be the exact grip, weight (slightly more than the SD9) and balance for me.
I second Gru on this one. I carry a Tristar C100 and also a Taurus PT111-G2. The G2 in the summer, as it's smaller and lighter with my summer clothing, but the C100 from about September until April. I really like the C100 the best, as the weight, balance, reliability, and accuracy can't be beat. But the Taurus has also been failure free for me and I've put about 800-900 rounds through it.
Just my $0.02.
