parts booklet says these are factory fitted parts that are sold on an exchange only basis.

Mostly because Ruger is the original "Lawyer Special." They're super-cautious about liability, especially so since the SR-9 and LCP "drop-gun" disasters. It's got nothing to do with fitting and everything to do with Ruger being gun-shy about lawsuits; the same reason Ruger weapons have a paragraph on the barrel and crappy triggers.

I have tried to do this with 2 HD Military H series pistols and it wouldn't work so please don't tell me they all interchange perfectly.

Probably because those pistols were built in the Way Back When and their components were worne through use, making them incompatible. Slide interchangability is a given on modern production firearms with the frequent exception of 1911 pistols. The 1st Gen S&W Sigma, in fact, was nicknamed the "Swock" because you could drop a Sigma slide onto a Glock, or a Glock slide onto the Smith & Wesson, and both weapons would fire and function as designed. S&W lost a major patent-infringement suit over that, and had to redesign the Sigma's upper end significantly. Likewise, I can swap slides around on any Glock, XD, M&P, (on the same weapon type: an XD slide will not fit a Glock) etc...provided calibre is not an issue and the weapons have the same length barrel and slide assembly.
