The supressors that come from the factory, especially yours Spit because your would have been one of the first out, are made of a very soft componud causing your problem. I had the same problem with mine and contacted Mathews Tech dept. and they admitted that the original ones are too soft and they have since come out with a harder compound version that will hold up better. Check the Forum at Mathewsinc.com and you can see this is not a rare problem. Here is the email that was sent to me. Hope this helps ya. Cya in the morning!!
***There is a new suppressor finger that has more material on the back side to cause the suppressor finger to recover faster, that is correct. I will send you a set of new suppressors direct via the address below.
