BudsGunShop.com - 70s or ?

Kimbers are neither a Series 70 nor a Series 80. The Swartz safety are parts that don't exist on either a S70 or S80. From the factory, Kimber uses a Series 70 extractor, a Series 70 grip safety, a Series 80 firing pin stop plate, and a proprietary firing pin (esp. for the Swartz.)

Randy is actually on point here. Read the thread at the address below. It addresses this question/issue in depth.

Hi Timothy and welcome. This model is a Series 80. Cheers and stay safe!
