I'm thinking about ordering a PAM (someone shoot me, I said I never would). Anyways all these damn numbers are killing me. If someone could just tell me which one's are the 47mm, then I could find one I liked. Everyone that I think I like (111) is 44mm. I also want a real good one, and I'm not the biggest fan on the "fiddy". Any help would be appreciated. Also is it better to order from someone like davidson, then someone like Joshua when it comes to a PAM? thanks!
