  • They have a safety device on the trigger. It amounts to a little plastic piece in the middle of the trigger. Pressing on the trigger from the front causes this piece to slide in, allowing the trigger to be depressed. It doesn’t do much but it would prevent the trigger from being pulled by something scraping it from the side, as might accidentally happen during holstering. It seems like the point of this device is to prevent accidental trigger pulls.

    When you pull back the slide and chamber a round, you also pull back the striker. The gun is then ready to fire. The trigger pull is always the same weight. This doesn’t put the gun into an “extra light trigger pull” setting. After a shot is fired, when the gun cycles, this chambers a new round and pulls the striker back again. There’s no way to have a round chambered but not have the striker pulled back. Glocks don’t have a single action / double action like there is on some other guns, where the first trigger pull takes extra weight because it’s also cocking a hammer.








  • These antigens are mainly significant in regards to blood transfusions.

    People generally don’t create antibodies against antigens that they have on their own cells.

    If someone receives blood containing an antigen that isn’t present on their own cells, and their body has already created antibodies against this “foregin” antigen, this can cause a hemolytic transfusion reaction (the transfused blood cells will rupture in the recipient), which can be fatal.
