This is something I learned over on the Pistolsmith forum, thought I'd pass it on. All you gunsmiths(You Kevin, Mr.Sweeney, etc) and notable 1911-mechanics will like this one.
Seems there's a problem with some Series II Kimbers with the new firing-pin safety. This is one of those 'Either it happens from the beginning or it doesn't happen things. Seems on some Kimbers the arm attached to the grip-safety that pushes up the plunger and releases the firing pin isn't long enough. The slide will release, the hammer will cock but, the gun won't fire when the trigger is pulled. Most people send the gun back to Kimber for a replacement, looking at 4 to 6 weeks here in Kimber's warranty shop. Well, there's a way to fix it in fifteen minutes, install a Colt firing-pin. they're identical except for the notch in the Kimber pin that the firing-pin safety block drops into. The Colt firing-pin holds the block up out of the way and it just rides on top of the pin without any interference. If the gun has to be sent back for any future warranty work, just swap the pins back out.
To change out; Strip the pistol down for cleaning, take the slide in one hand after you take the firing pin stop out, stick a small punch into the plunger-hole and push down onto a table. This pushes the block up and the firing-pin backs partially out. just reach and pull it out. Install of the Colt pin is the reverse.
