Here's a better link to the solicitations and amendments. While the specific models haven't been announced (where I could find them, anyway), if you read the updated amendments you'll find references to "full size" and "compact".

In the S&W line that would mean the M&P 40/40c, and in the Glock line the G22/23. If this is how it came down, and the G27 wasn't requested or submitted, then it would seem S&W has a potential advantage for some users since the M&P 40c "compact" is actually more like the G27 than the G23.
EDITED: Someone on another forum took the time to read through the specs and observed the G23 doesn't seem to meet the "compact" dimension requirements, so perhaps the G27 is what was being tested (regardless of what Glock may label their models regarding "size"). Good catch. The press release will probably be forthcoming pretty quickly to resolve any questions, though. Besides, when you think about it, the BATFE does have intimate knowledge of the guns made by each firearms company, so if they submitted a size specification it would seem reasonable to suspect they knew exactly what models would meet their requirements in that regard.
M&P 40c & G27:
I suppose we'll see as time passes and the details are approved for public release.
No, both S&W and Glock "won".
The long & short of it is that these contracts are apparently the largest non-military small arms contracts in U.S. history.
Congrats to S&W and Glock. (Especially after both failed to win in the earlier DHS testing
).
FWIW, I wouldn't worry about the 'commonality' of either parts or magazines. Look how NYPD has supported the choice of S&W, Sig and Glock by its officers for years.
"Parts is parts" and both designs are relatively easy when it comes to armorer support (I'm an armorer for both Glock and the M&P pistols series).
