The Bullet Hole in Overland Park KS also has HKs for rent. The Bullet Hole
They've got p30 and VP series, in 9mm and .40SW. Did NOT have any LEM variants for rent the last time I went there, about a year ago, and at that time the variants of the p30 they had were v3.
Nice place to be able to put some rounds through one to try it out, but their target hangers leave something to be desired, as they swing from side to side when you send them downrange.
