First off, you have to decide if you want an SD can that is made to mount to a factory spec gun. RDTS makes a nice can, and besides the extra weight, does not mount on a factory spec barrel. However, I "think" he may make one to factory mounting spec if special ordered. TSC makes a copy of the factory can, however, I've asked Mike in the past if he were going to make these as a stand alone item, and he didn't show any interest in that. I think all the time he puts into it, he would have to charge more than people would be willing to pay. Otherwise, he just absorbes the suppressor work into his total SD build price.
