MK9 again
You spent your money well, you will definitely be happy. Just do not shoot lead in it. The laed will spray out of the 6 holes in the tube that slides over the barrel, making difficult to get out of center core if you try to take apart. I spray mine with MIG anti spatter spray, it is a greasy mess when taken apart.
A lot of people state "it's too big, old technology".... But Doc Dater designed the can, and he will tell you "it is still a work horse today".. You will like it, especially when you use sub-sonic ammo. Refer to the thread for the "Homemade suppressor tool". When you install the AWC, grasp the tube and turn it, may find it /caps loose. After you get it hot, wearing a glove, tighen it again, as the aluminum expands, after that you should be all set.
Enjoy it, it should serve you really well.
