There are not any listings for aftermarket sights for the 1911-22. There are sights that will fit, I just need the size of the dovetails on the slide to locate a set. Some of the pistols have a front dovetail and some have a staked sight. Which does your gun have?
I will check the dovetail size on my gun and get back to you as soon as I find a set that is the correct size.
The rear dovetail is 0.265". The front on mine is a type of staked in sight. Does your gun have the same or a dovetail?
I need to call Browning tomorrow to see what they have available, they do not have a parts listing for the 1911-22 on their site.
