Questions that need answered in the details:

1: Is the spring in the picture included? If so, what strength is it?
2: What is the cylinder made out of? I assume aluminum, but we must know before buying.
3: Is the entire trigger box made out of steel?
4: Are the sears 1 and 2 included? If so, what are they made out of?
