My first 1911 was the TLE, too. I've had it a couple of years now and it continues to be a highly reliable, accurate, dependable handgun!! The only problems I've had with it were feeding and ejecting when I used some reloads a friend gave me. With new manufactured ammo it has run flawlessly.
You can get magazines that hold one more round ( 8 + 1) for it. I bought a Kimber mag that has a slightly different follower which allows the additional round.
Now, for your next Kimber, take a look at the CDP Pro or Compact. Either of these will be a better carry gun than the TLE because of the rounded (dehorned) treatment. I couldn't resist and picked up one of these, also.
I agree, you need to run around 500 rounds thru the TLE to smooth its functioning out. Also, if you get some .45 snap caps, you can do nightly dry fire practice while watching TV. This will help you get used to the trigger, and it will improve and smooth out of the trigger without the cost of additional ammo.
One or two 1911's isn't enuf, tho, I now have two more - a Wilson and a Dan Wesson. My wish list now includes a Rock River, a Les Baer, and a Nighthawk. It's difficult to turn off this 1911 craving!!! I suspect you'll become addicted, too. If you do, just accept it and enjoyj!
