On Tuesday I picked up my first glock and I had some questions on what I should purchase for my new pistol. Here is some basic info on the gun: it is law enforcement trade in with night sights already installed, in addition it came with one 10 round magazine (I live in California) and the glock case. I had attempted yesterday to call glock to aquire info on the guns manufacture date and such, but I didn't get hold of the individual who could give me that info. I also looked on this site at the serial prefix list, but it skipped my set which is EHD. I know it is a generation 3 and all three serial number on gun match (slide, barrel, and reciever). I really would appreciate any information in regards to my new glock. I am very excited about it and can't wait to take it out shooting.
