Well JD, the way it "should" be, is that you should have to remove the lower tang! The one that come apart without doing that are actually the wrong ones

RD, I do like you do when I have a tight fitting lower tang. And remove some off of the sides and edges of the tang and receiver, until the tang goes in and out without any hassle.
