Dude, if you need some clips, let me know. I'll mail you some.
I don't know how familiar you are with Garands, but:
Please don't shoot commercial ammo that is not designed for the Garand. It will make us cry if you do.
Also, check out the CMP forums, there is a wealth of knowledge on there.

And here is their tech info:

There are also a lot of other sites and books that have tons of info. This guy is really well respected in the M1 community, has some good info on his site, and has written a lot of books on Garands:

Lastly, prepare yourself. I bought one not long ago, thinking I only needed one. Happily, I was very mistaken in thinking that. I hope to go to the North Store and get a Service Special if they have any left. No other rifle, shotgun, or handgun has sucked me in like Garands have. I imagine I will be buying them until I am too feeble to shoot them (and I'm 31!), and probably even after I am too feeble to shoot them.
PS - range report ASAP. mkay?
