I have a G-30 and I really like it the little I've actually fired it. What i don't like is the weight with a fully loaded magazine. I wish the 30 SF were around when I got the G-30.
What I carry everywhere and I wouldn't trade it for anything is a little Sig P938.
I bought a S&W M&P 45 Shield a little over a month ago. I haven't carried it and don't know if I will.
Anyone wanting a Shield S&W from 4/1 thru 6/30 is offering a 75.00 rebate on the 9mm ,40 cal and 45 Shields. The bodyguard 380's have a 50.00 mail in rebate. I wish I had waited buying my Shield.
