Shawn there wasn't a 40cal version. S&W realized it was probably the worst gun they've ever produced and stopped production after only a year or so. I had an SW380 and it was really a cheap firearm. If you want a nice little pocket gun look at the J-frame 5 shot airweights. I wear one on my ankle as a back-up and forget it's even there. If there's one type of gun Smith is second to none on, it's revolvers. Another option is the compact M&P9. I've read nothing but good about them and my full-size M&P40 has been fantastic.
