Agreed, Used my Mp5K t'other week as a backup whilst sniping, pulled the sling up so it was as close to me as poss and still grab-able, folded the stock in (first time since forever haha) and had a blast Only took it to the woodland site as it was in the bag and I couldnt really be bothered to unpack it, having only used it indoors before I was really surprised with the range too.
But still love my pistol as an ultimate backup / CQB weapon.. I think you should give it a go, pistols are great fun to use....
