I'm probably over simplifying, but I consider the 4516, both flavors of 4513TSW, 457 and their DAO equivalents as compact.
LOL, yes it is but it's a large frame & the barrel is actually 3.75" long.
I should have added the qualifier to my statement that the pre-rail 4056TSW is the only compact medium frame all steel 3rd Gen pistol, which is what I usually attribute to it's uniqueness. My error.
