Hi Victor, since we are customers like yourself, we do not have access to firearms. I doubt if Langdon Tactical could even tell you without the serial number, since each gun can have so many different configurations. The only thing I can say for sure is it has the LTT Trigger Job with Optimized Performance Trigger Bar and 11# Hammer Spring, since they all have that.
Bud's is in possession of the gun and should know exactly what else was added. 1-859-368-0371 9am-8pm EST Mon-Fri.
