never said i could, and nether can you, and from what you described it was a malfunction, however i can do them in .11 with full pf loads, but with downloaded 45's i have had to wait because the slide is slow, it may very well be in battery, but not fast enough to acquire the next shot in the same amount of time as full pf loads in a .45, comparing a malfunctioning glock with it is apples and oranges, i did not know the origin of this question was about a glock, i give my experience with under powered 45's, now if you want to ask about glocks start another thread
