Maybe i can help
Chad---guru1911 here to maybe help you. When you said the firing pin would not "reset" were you referring to "would not cock" ??? If that is correct do the following:
1. Remove the two pins which hold the trigger / hammer / sear group in place.
2. Gently remove the trigger group from the bottom of the receiver & inspect it under strong direct light. If the mechanism is impacted with hardened grease, lube, & dirt, fill a plastic dishpan with about 1" of simple green diluted 50/50 with h2o. Put the trigger group into the dishpan. If you have a vibratory power tool such as an orbital sander, turn it on & touch it against the side of the pan---tada--you got a giant ultrasonic cleaner really cheap !!!! While the trigger group is in the tub, clean the innards of the receiver as best you can.
3. After a few minutes in the pan, check to see if it is clean. If not, back in it goes. If it is, then rinse in hot water & blow dry with compressed air, then use a portable hair dryer for the remainder of any moisture.
4. Lube all moving parts & install back into the receiver. Pull back on the bolt & let it fly forward. Take off the safety & pull the trigger---it should go click !!!!
Let me know if this fixed your problem. Thanks !!!!!
