TPM Outfitters 8 Inch K-Sized MP5SD Silencer

Over the past couple months there has been three separate announcements that include different models of silencers designed specifically for the MP5SD – an iconic roller delayed sub machine gun chambered in 9mm featuring a ported barrel for maximum suppression. This includes the just announced eight inch offering from TPM Outfitters.

If you are concerned about performance with a smaller can, Ken and Matt at TPM have conducted side by side testing of the new ‘K’ sized SD can next to the full sized (12″) original-sized SD can. The sound reduction difference between the two is negligible.

As you can see from the below pictures, the four inch difference makes for a much more compact package. And with similar suppression, there’s not much of a downside to the shorter length unless you are looking for that authentic MP5SD look.

One of the best parts is the price.TPM Outfitters is retailing the new silencer at $440. Additional pictures and contact information can be found below.

    After years of seeing the normal SD suppressors these K-cans like this and the Silencerco option make the gun look really goofy.

    I know that technology has come a long way and they work as good or better but still, they just look wrong.

      I like them though, Hella handy. Suppressed MP5 the size of a regular MP5.

        I don’t dispute any of that and it makes sense.

        But you have to admit they look weird.

          Y’know what looks weird?

          YOUR MOM! OOOH, BURN!

          Yeah, sorry. you’re kinda right. Though I like the look ,it looks a bit like a sawn off.

            I don’t mind the look at all, but I like stumpy guns so no big surprise I guess

        With the bullet energy of a 380.

      I agree, just looks weird and wrong to me as well.

    Do they make an MP5 SDQ version?
