the kimber tle is the same as the kimber lapd swat model. just different serial numbers are used.
yes to tritium sights.
lapd swat members get two kimbers, one without light rails and one with.
i love my tle, and if i had to do it over again, i'd definitely buy another tle. except maybe in stainless, and hopefully it would have the internal extractor.
there is also a tle with a 4 inch barrel.
if i had a few extra hundred bucks, the kimber custom eclipse would probably tickle me just as well. put the two of them side by side and you can see where the extra money goes.
