Purchased today, pick-up sat. My older kimber classic custom is a hell of shooter, few minor touches from stock.  How do the series II differ from the older guns.  Is it basically the difference of series 80 to series 70 in colt lingo or is it more?  I had a para limited 14-45 that I converted to series 70 with a frame filler from brownells, this helped trigger pull quite abit, was wondering if this is possible with the series II.  The trigger wasn't bad on this kimber, other then a little more takeup than I like, but thats easily fixed, or at least it is on a single stack.  Figured that and a 19# mainspring would make this a nice service trigger.  I guess the trigger has the tabs on it for adjusting takeup, anybody know for sure though?  Thanks in advance for the knowledge.
