Do you just want the long blued slide? I have seen blued LS standard models before, but EAA apparently wasn't consistent on those.
Alternatively you could just pick up a cheap standard frame and drop the LS kit on top. You won't have the extended safety, so if you're a 1911-pointer kind of guy you'd need one. LS conversion kits are $285 from EAA. You'd be out $710 up front and you could sell the standard frame top for $200 as a "conversion kit"
That's true too, I'm still kind of torn on how to proceed. But just knowing myself, it'll be alot easier for me to come up with $160-ish for parts, piecemeal if nescessary, than another $300 chunk on top of $400 for the standard frame. And I'm becoming entirely too fascinated with the inner workings of guns and how I might tweak them
