I would like to purchase an M & P 22 and place a suppressor. Does the 22 come with an external threaded barrel already in place or do you buy an adaptor to fit the suppressor? What is a good suppressor for the gun? Thanx for your help...Dr Bob
One thing to keep in mind - you will want a suppressor you can take apart to clean. Rimfire ammo is extremely flithy and will cruddy up a suppressor quickly. All SilencerCo rimfire suppressors can be taken apart for cleaning. The AAC Pilot and Tactical Solutions Cascade are examples of "sealed" suppressors that can not be taken apart to clean - but still, their intervals for cleaning are pretty high (1000 rounds).
If you shoot jacketed bullets any rimfire can will be fine. AAC states in their leaflet that the Pilot is NOT to be used with lead ammo. This is the reason I didn't buy the AAC Pilot. I personally own a SilencerCo Sparrow and TacSol Cascade, and they're both great.
