From what I've seen around the boards and at my local fields in So Cal, it does seem to be a common issue.
I am in no way trying to tarnish the KWA name, considering I loved my USP and I absolutely LOVED my hk45 for the first few weeks...however I have been seeing a lot of the same problems popping up.
I appreciate all the help on the boards aswell as KWA and I'm hoping we can get this problem resolved so I can continue using KWA products.
Please do also understand that this is a technical board. Generally when people come onto this board they have issues, we have sold thousands of these guns and we have not seen many reports about this problem.
