BudsGunShop.com - Kimber ultra carry

Geoffrey, this 45ACP Magazine will function in the Kimber Ultra Carry. Tower and magazine catch slot are the same as the original magazines. Just insert enough to get the audible lock/click.

Geoffrey, Yes these magazines are 45 ACP size. Will fit and function in your Kimber.

They are 45 ACP magazines and should fit in the ultra/officer frame size but might be a bit less reliable than the properly sized magazines that are shorter. I would take care not to insert them with excessive force as the extra length can potentially allow over-insertion.
