Rear sight for Llama X1B

[pinstripe]

Is the dovetail on the slide of a Llama X1B the same as other 1911 type firearms or are they different? If they are different, what is the dovetail dimensions? I need to replace my rear sight with one that has an elevation adjustment, and can't locate parts for a Llama that will work. Mine only has windage adjustment, and I am shooting about a foot low at 25 yds.
Thanks in advance

look ahead

Why not just file the front sight lower until it's right?

I try not to bubba a firearm. I would rather spend the money and do it correctly. Just needing to know if the 1911 rear sight will work. Thanks for playing!
