Mark this would be true of most modern pistols eg. M&P from S&W and the P-01/PCR from CZ.

Probably true, but I haven't personally witnessed it, or taken part in it, and I'm not aware of any other manufacturers that make any actual claims about doing it. Having said that, there are probably YouTube videos of it being done. For Glocks, it is a regular thing at many shooting and demo events.
I was referring to the general interchangeability of modern gun parts, and probably original 1911s, compared to the more fitted parts required by modern 1911s.
As for those examples, there aren't too many being run by any Tier 1 units that I am aware of. As someone posted, the Glock 19 has been around for 27 years, and except for a little glitch with early Gen4s that has now been rectified, they just plain run. No need to reinvent the wheel.
Glock 19s don't really work as well for me as other options, but I am not a Navy SEAL, I don't have the same requirements. If I could carry concealed here in Canada as I have done elsewhere for over 30 years, I might be willing to sacrifice some handling for a more compact and concealable package (yes, 1/2 an inch either way does matter, if you don't believe me, just ask your girlfriend), but I have carried Glock 17s concealed thousands of times without issues.
Regards.
