Bought it for a kimber pro carry 2, and the gunsmith I took it to, to have it installed wanted too much to fit it. I have decided to stick with the stock one for the time being.
Price on the package says $36.95, it cost me $40, with tax, I ll ship it to you for $35, that is delivered.
Thanks for looking!
