just went out and shot this beast (sd40) yesterday and i love it no complaints wat so ever. 100 rounds no problem and cant wait to put more through it! the only thing she needs is some pants ne suggestions on a nice grip?

I have this grip and I like it:
Pachmayr Tactical Grip Glove Slip-On Grip Sleeve S&W Sigma Rubber Black - MidwayUSA

I have the same grip on my sigma 40VE. I would not be surprised if this grip would also fit the SD handguns also.

It would but I like the sd the way it is. The grip adds a lot of width that I think makes it less attractive.
