UK legal, long-barrelled version of the Walther PPQ in .22LR calibre. Made in the Walther factory by Walther, it is identical to the version found in the rest of the world except for the 300mm barrel and "coat-hanger".
What Walther say:
THE FINEST RIMFIRE HANDGUN
The PPQ .22 is the best of both worlds. By combining smooth-shooting, ergonomically-advanced components of the PPQ with the fun and cost savings of .22 rimfire, you have the pleasure of shooting shot after shot both accurately and affordably. The sculpted grip meshes smoothly into the hand. The trigger is the finest ever on a polymer handgun. The styling is elegant and trim.
