Huge in dimensions, heavy, overpriced, lots of bits, pieces, pins, and springs inside, and middlin to poor ergonomics -- and it comes with the famous H&K superiority "take-it-or-leave-it" attitude that H&K has towards non-LEO customers, i.e., the public. Had a used one that I bought in a moment of weakness and regretted it soon after; something I rarely do with a gun purchase. Let my heart make the purchase, not my head; after all it was and H&K for Pete's sake!
IMO, the SIG 220 is everything the H&K should be, but H&K just had to go "bigger" and they blew it.
Sort of comparing a Jeep Cherokee Classic to the full-size Hummer H1.
Gimme the Jeep, gimme the SIG.
