Why do you think the M&P did not meet modularity requirements? The M&P had modular back straps just like the Glock. The gun was withdrawn after testing. IF they have been released then you should check DoD's DOT&E as they ran the tests for all of the pistols submitted.I cannot find the actual results of any testing during the MHS selection process for the M&P or the Glock. The only information I have been able to come up with is that the M&P did not meet the modularity requirements, which were obviously written for the P320. Do you have a link to test data for the MHS entrants?
The modularity requirements were not written for the 320. Some pistols went with backstraps, SIG went with different frames.
