I'm glad to see that picture! I had a 3" GP100 a couple of years ago, and foolishly traded it away. I have regretted it ever since, and I haven't been able to find another one. I went into my local gun shop today to buy a SP101. As I was looking at them, I casually mentioned that I wished he had a GP100 in 3"...he grinned at me, reached under the counter and pulled one out! It was NIB, and marked $550...I didn't even hesitate on the price, and it is home with me now.
I was going to order some Pachmayr grips for it, but now that I've seen the pictures above, I'm thinking I'll see if I can get some compact grips for it. Or maybe both! The stock grips that come on it are just too big.
