Going through some threads I'm subscribed to, I noticed a few months ago I asked the same question in this thread's title except for the .45 ACP only. I thought I'd start a thread using the .40 S&W round only.
Of the three models above, only the M&P was designed from the get-go for the .40 S&W. The XD was originally designed for the 9mm. The Glock was designed for the 9mm as well for generations 1 through 3. However, I read something along the lines that the Glock Gen. 4 in .40 was designed especially for the .40 S&W.
