Today I went by the store where I bought the pistol for some more range time. Before going to the range I stopped by the sales counter and checked out the Glock display. The sub-compacts I looked at all had the protrusion. Guess I'd never really paid attention to it before. My shooting partner has a 27 and was surprised he'd never spotted it before either.
