As a retired cop, I get it. Retention holsters, some of which require rocking or twisting to release, are easier to use with a full-size grip. When the release is accomplished, there's less slide to get clear of the holster. This is particularly nice when you are forced to draw from a seated position. The shorter slide means a shorter overall duty holster may be used, which translates to less duty holster jammed into the seat. One less PITA for folks suffering with a bat-belt full of equipment. My only complaint would be the platform isn't available in 40 or 45 yet.
