the 207 is hard plastic and a strictly price point seller.
the real choice is between 306 and 308.
306 is my suggestion as the trigger reach is much shorter.
you can always order both and send one back(on line) or find a good full line retailer that actaully has both on the shelf.
big box stores are unlikely to have the 306.
good luck
