I am looking to purchase my first M1 Garand through CMP in the next few weeks. I am a complete newbe on the M1 so would appreciate any pointers. I was looking at both the Service and Special Grade rifles. I wont be putting the rifle on display, do plan on shooting it - but not in competition, and have no real requirement other than wanting one. With that as background, would you recommend Service or Special Grade? What other pointers to look for?
