DA/SA is harder to double tap with than are trigger systems with consistent pulls from first to last. Not that it can't be done, but it takes more work.
The 1911 offers a relatively light, consistent pull with short travel and short reset.
The Glock isn't as nice, but is closer in character to a 1911 than a DA/SA. The Glock can also be loaded to 10+1 for IDPA, and often will not require a reload in a string of fire where a 1911 will.
In those strings that exceed 11 rounds, I find the tapered top of a double stack magazine is a bit faster to insert in the well by feel than is the tighter fit of a single stack.
Personally, though, I prefer M&Ps over Glocks, and 1911s over M&Ps.
