dave, it shortened the duration of theshot noiseby about half, if that makes sense... I think it may also help in the coldest winter months when I'm wearing my super-thick wool Predator bomber jacket from Gray Wolf Woolens.

Hitting my sleeves has never been a problem, as I shoot with a pretty good bend in my elbow... but it's nice knowing that if those puffy sleeves did get in the way, that the supressor would stop the forward movement of the string.
