Well, I think besides the stock, the 10-round mag, and the fireing pin the most complained about part of the gun is the trigger. Mostly its the heavy pull, but sometimes also that its plastic...... untill now: ***Please note: The black one is the original one, the silver one is the prototype.*** This is the prototype, need to go buy some small drill bits for the two pin holes and the spring hole in the back. Also, need to figure out how to cut the slot in the back. If everything works out ok and there is some intrest in it, I may make a small production run. What do you guys think?
