Impact Wrench socket compatability

I have a lithium ion Milwaukee M18 3/8" impact wrench that I bought earlier this year, it has the friction ring. M18 Cordless Lithium-Ion 3/8" Compact Impact Wrench with Friction Ring Kit | Milwaukee Tool

Now, I'd figure just any impact sockets would work, so I bought some Tekton impact sockets, but they have the indent for the retaining pins?

http://www.amazon.com/TEKTON-4790-Sh.../dp/B000JKP24U

So, I'm not able to use these sockets as they don't hold. I went to Home Depot, Lowes, and Sears to find an adapter, but I couldn't find anything.

Is there an adapter or are there special sockets for this impact wrench?

Thanks!

I've never seen an impact wrench anvil with the retaining pin - none of my three do.

Mine both have rings, and, can't say that I have pulled out every socket to try it, but, as far as I recall, all of my sockets, impact and others, fit. But I'm not sure that I own an impact or sockets that are newer than something like 30 years old either.

What do you mean the sockets don't hold? Most impact gun, both cordless and air, don't grab a socket like a ratchet does, they usually just sort of friction fit on the gun, and will fall off easily. Is this what is happening?

I don't have a cordless impact but on my pneumatic impact, every 1/2" socket or adapter [impact or regular] I have fits snug enough although I always cup the socket if giving the impact a test run. If the socket just falls off of the anvil - I'd suspect the gun is defective.

At the end of the anvil for your 3/8" impact gun should be a hog ring. The ring is what holds the socket from just falling off. Every brand of impact gun I've ever had and even my newer ones have the same ring. When the sockets fall off too easily you can replace the ring.

Milwaukee sells them in a kit for your gun.

Yes, it'll just fall off. I don't think it's defective, I used it probably twice this year. I was trying to use it on a large bolt this morning, but the anvil just kept on twisting and spinning. Yes, they're both 3/8".

There should be a rubber o-ring under the steel spring ring, is it still there and in one piece? Usually those go first and once they do, the anvil hits the ring and wears it down fast. As pointed, you can get a new kit, good luck.
