Frankly, it's too small. The gun is a standard WE Gen 4 G17 with a custom installed fibre optic red foresight, the orange fibre optic rear sight off my WEI Tech slide, a Silverback laser grip, a RHC Magwell and RRL, and a large amount of tape on the grip. Oh, and an 11mm to 14mm thread adapter on the front. My MP7 was shooting hot that day, and my backups were all in the shop, so I was pistols only that day. Absolutely brilliant, and the gun preformed flawlessly, even though it was a bit cold.
