Quick shipping and I have it in my hands. Havent had a chance to try it out yet. Fits my 550 and 551's but it is a bit tigher than the original.

I thought they weren't for use with the 553; only the guns with the larger piston.

Opps, you are correct. I meant 551 not 553. I bought it to suppress my 550 since B&T makes a can here in the US that will mount on my 550. Also will be using it on my Sig 551a1.
