I really do not understand why SW did not at least give the option of using a silencer on this quite awesome pistol. I've put about 1500 rounds through mine with few failures and most of those were typical rimfire fail to fire. that said I really want the option to use a silencer but I do not want to buy a walther or keltech to do so. They made the 5.7 with a threaded barrel, why the hell wouldn't they have done so for this great pistol?
