This one is probably silly.....I just got a silverback the other day and while I love it, something seems off. On the first few shots it releases as soon as I let off the safety but after maybe 10 shots or so I'm pushing and pulling hard trying to get it to release. Could this simply be fatigue/variation in my form or an issue with the release itself? I'm guessing user error but it seems like a wide gap to go from firing from releasing the safety to really struggling to get it to break.
