Same, XP-G3. Yes it isn’t a lightweight for sure. Nice light though. Wicked bright. I really like it. Just don’t use it. It’s become like jewelery for the shelf. Too heavy to carry everyday. As you mentioned the knurling is quite aggressive. I did try to carry it for a while but the knurling put a serious hurt on my pocket. Might not be so bad with a holster. I got one but the knurling eats up the inside of it. What is wrong with me, I am talking people out of buying it.
