I recently bought 2 Camo Super Vinchis for Christmas. One for myself and one for my 13 year old son. We use them for duck hunting in eastern Arkansas. When he shoots his, the trigger guard slams his finger. He tries to keep his middle finger taped up but it still gets beat up. After hunting this morning, his finger is swollen and bruised. Any one else have this problem? If so, what was your solution?
