This correct, if you remove the backstrap the gun is disabled. This is their trademark QuckSafe feature and I have heard that repeated removal can cause the latch to fail. In the instructions it tells you to remove the backstrap when you strip the gun. This is not necessary and everyone recommends you leave the backstrap in place. If you do, all you need to do to remove the slide is release the striker from half cock by pulling the trigger, just like a Glock. I should remind you to check the gun to make sure it is unloaded. . . then check again. . . and again. . . and maybe one more!!!The only negative I've read is something about if the the snap on back strap comes loose, the gun becomes inoperative. I don't know how much of a real life issue this is, but I mention it as some people seem to be concerned.
