I have an old T/C Thunder Hawk. About 5 yrs ago I needed a bolt spring and other related parts. I called T/C service, in 3-4 days had the parts at NO charge. Cannot beat their service. On the other hand I have a Knight .45 disk. I love the gun,never a problem. I called them and e-mailed when I purchased the gun(hottest new smoke pole on the market at time). Bottom line - They can't hold a candle to T/C service !!
