Adjustable dual stage trigger assembly

An adjustable dual stage trigger assembly comprising:

• a spring activated hammer, a disconnect lever, and a tension adjustable spring loaded trigger;
• said spring activated hammer being pivotally connectable with a first pin through a receiver cavity of a firearm and having a hammer notch and a hammer tang;
• said tension adjustable spring loaded trigger being pivotally connectable with a second pin through said receiver cavity and having a trigger sear fully engaging said hammer notch when said firearm is in a cocked position;
• said disconnect lever also being pivotally connectable with said second pin and being operably connected with said tension adjustable spring loaded trigger;
• a first threaded adjustment means, adjustable by a user of said firearm, in said disconnect lever on one end of said disconnect lever and a second threaded adjustment means, adjustable by said user, or an opposite end of said disconnect lever;
• said first threaded adjustment means allowing said user to adjust lengths of contact faces of said sear and said hammer notch to have desired engagement of said sear and said hammer notch;
• said spring loaded trigger, said hammer tang, and said disconnect lever being so shaped and sized that a contact portion of said disconnect lever contacts said hammer tang on said hammer simultaneously with said user adjustment to have said desired engagement of said sear and said hammer notch;
• and said second threaded adjustment means acting to compress a spring against said trigger thereby adjusting trigger pressure needed to fire said firearm after said contact portion of said disconnect lever contacts said hammer tang.

An adjustable dual stage trigger assembly in a firearm comprising a spring loaded hammer means, a disconnect lever means, a user adjustable spring loaded trigger means, and an engagement means to engage said hammer means with said trigger means when said firearm is in a cocked position;

• said disconnect lever means being operably connected with said trigger means and having a first user adjustable screw to adjust said engagement means to a user desired engagement without disturbing said assembly and causing contact between a tang on said hammer means and a contact end on said disconnect lever means;
• said disconnect lever means further having a second user adjustable screw to compress a spring to adjust pressure of said contact end against said tang and cause an additional resistance to a pull on said spring loaded trigger means, said additional resistance being in addition to an adjustable spring loading on said adjustable spring loaded trigger means;
• a first stage movement of said dual stage trigger assembly ends when said contact end of said disconnect lever means contacts said hammer tang;
• a second stage movement of said trigger assembly to cause the firearm to fire, ends with additional pull to overcome said additional resistance and disengage said engagement means.
