Hehe, funny to see myself quoted from a year ago!
No such thing as a Kimber TRE. They make the *TLE* and the TLE/RL (railed model).
TLE stands for something like "tactical law enforcement" (or something) because it's apparently an exact copy of the Kimber used by the LAPD SWAT, known as the "Custom II" or the "LAPD Custom II" (can't remember which).
Hope that helps.
