First time since I started EDCing my Monadnock Ayoob D-Jammer about a year ago, it came out for a purpose. Not for SD, thank goodness. We were out at the range, and my father-in-law had part of a 9mm case separate inside the chamber. Without the D-Jammer, or a cleaning rod, it would have been stuck in there, and the gun out of commission, until we got back home. As it was, we had him back in business in just a few seconds. A good piece of kit, indeed.
