When Tru-Fire designs a new product, we want to make certain it gives you, the consumer, years of trouble-free use and dependability. One of the first issues we address is using the same material on the internal firing mechanism. This is important because when different metals with different hardnesses are combined in a firing mechanism, premature wear can and often times will occur. Be careful, other release companies firing mechanisms are made from different metals altogether. Tru-Fire, on the other hand, designs firing mechanisms to utilize the same metal and hardness on all of our release firing components.
