Might be old news to some of you, but tuffproducts.com makes a speed strip (they call it a quick strip) for the .22 Magnum. Holds 10 rounds too! Just got mine in the mail today.
Be advised that they make a different one for the 22LR.
Now I have 22 Magnum ammo, a holster, and quick strips, but still waiting for the 351C to arrive
