HAJO sight is a nice to easily get a height adjustable rear sight (if you want that) on a standard shadow, but it is taller, sitting more on top of slide. You can get LPA target sight option which is just about as low as fixed sight, but adjustable, it's just a custom sight cut to get when you order, or having it done later.
so the LPA Rear sight will work on SP01s??
its impossible to get CZC on the phone.
