has anyone had issues with this ammo in 40sw. I have a 40xd and at the 3rd mag it started to jam I had about 6 jams out of 140 rounds. What gives? I have a glock 27 never jams, I have a daewoo 9mm I bought in 1994 and as of date no jams. Could it be the ammo? i have only put about 300 rounds through it since i bought in May 08 it dam jam before also.
