Good afternoon AR15.com..

I picked up a 1911 slide off "blackthorneproducts.com" ,
The dimensions are listed as....."the rear is machined for standard pattern adjustable sights (.330 x 60 degree x 110" with .500 flat forward and .258 to the rear cut.  Bottom of dovetail to top of slide is .138") and the front is machined for a standard dovetail front sight. .330" x 65 degree x .060 dovetail. Center of front dovetail to front of slide .325"

I took a quick around trying to find the right size and grab a cheap set or sights, I believe these are supposed to be just your standard novak sight cuts bUT none seem to be exact fits. I don't mind filing down a set to make it fit but spending around $100 I'd prefer an exact replacement. Can anybody send me in the right direction?

Thanks in advance, any info would help.

Now bear with me because I'm trying to do this from memory and I'm a feeble old minded gunsmith.  

Okay so I took a look at the slide and read the copy below it.

Front sight:   330x65 is normal, but it's the .060 that's weird.  IIRC they're normally .10 deep, so the front sight cut seems to be shallow.
Rear sight: The rear cut is sort of "Bo Mar-ish" in appearance.

But it says they were made for LPA sights.  I would think the thing to do would be to contact LPA and see if they can hook you up with the appropriate sights for that slide.
