I picked up a S&W M&P 22 a few weeks back and have been having a good time with it at the range. One of the cool things about the M&P 22 is that it comes with a threaded barrel. Knowing that I already had a threaded barrel that would take a Walther P22 adapter I couldn't pass up on getting a thread adapter and flash hider combo from Tactical Innovations: http://www.tacticalinc.com/walther-p22-thread-adapterbrand-flash-hider-combo-p-433.html. My new toy came in the mail yesterday: I think it looks pretty sweet on the M&P 22 and, while it may not be a real flash suppressor, I put 250 rounds through it today and the added weight makes a real difference to muzzle rise and felt recoil. I was really surprised at the difference it made. If you have an M&P 22 you should take a look. It is well worth the price.
