Ruger micro sight height/interchangeablity

[MidRoad]

Hey was just wondering if anyone knew the notch size that comes on the Ruger micro sight that comes on the current flat tops. Also wondering if anyone knows where I can get a replacement blade that is just a little bit wider than the factory one. The micro sights are nice but I have cruddy eyes and would like just a little bit more light to come through between the post and the notch edges. I put a .100 blade from Dawson's and blacked out the rear on my 6" gp100 and that helps me be more percise,and it's easier for my to get a nice sight picture. So I'd like to try it out on my flattop. The flattopis blued so a front sight change isnt easy as drilling and pinning, therefore i don't plan on changing the front sight. Thanks.

I found a few different sizes on eBay 90 .125 ,.140 widths. And .256 or .3 height .Don't have micrometer at home to measure mine . none of the ones on eBay mention new micro sights ,just says doesn't fit old micro sights?

Edit:
I did a redneck measure for the notch width. My 7/64 Allen wrenches fits with a little room to spare (.109") and the 3mm can't quite fit (.118") so the sight is .110-.117 . I'm thinking .125 would be ideal for me than. I see some .125" Ruger blades on eBay, not sure if they inter change with the micro sight or if the height is right , i ordered one just to try...

Ok , so just a fallow up to get the info out there in case someone in the future asks the same question. The sight blade came today came.

Rugers standard sight blade that fits marks 1,2,3's, gp100's and Blackhawks are interchangeable with the Micro style sight. The micro for a factory black hawk with a 5.5" barrel is .115" wide and the blade is .256" tall.

So the .125" blade I ordered fits perfect and gives me the sight picture I wanted. Here's the two blades. Top is factory, bottom is the one I ordered.
