There is very little difference between 1911s and Glocks in their operation. Neither are blow back designs, they are both a short recoil operated design. The locking block on the Glock works exactly like the barrel link in the 1911,(disengages the barrel from slide), and the barrel hood on the Glock works exactly like the barrel lugs on the 1911,(locks slide to barrel).
The Glock doesn't have a hammer, but it doesn't have much to do with the lockup anyway. The hammer spring does provide additional resistance to the movement of the slide, but once again, this is more relevant to slide movement than lockup.
