Yes, it is very simple; the backplate conversions work by mounting a forward-pointing "wedge" off of the backplate, and the angled portion of that wedge engages the rear part of the trigger bar, so that after a shot is fired and the slide is moving back into battery, the trigger bar tries to reset as normally, but just after the barrel rises back to lock into the slide, that "wedge" forces the trigger bar down just far enough to let the striker slip off the trigger bar, firing another shot (and so on, until the mag is empty). It's simple enough that some of the "competition" triggers can produce FA fire accidentally, because there's not enough engagement between the striker and the trigger bar, so the slight rise of the slide as it goes back into battery will do the same thing.
