I just bought an XD-40 had it out two times now. My friend has a glock 9mm. He only had it for a year and it is about the third time useing it. Both guns where clean and oiled when we went out today. I fired 100 rounds saturday and on Sunday we both went out after about 80 rounds fired his Glock started jamming. By the end of the day we had shot about 200 rounds from day one my XD has been flawless. His Glock jammed about 8 times..... All I could think of was good luck to the Glock lovers.
