Own both. If I was looking at a 9mm / 40 cal., I would choose a Glock, as the trigger is better then the S&W, and grips are comparable, if different. As noted above, proven Honda Accord like reliability.

In a 45 acp, I would pick the S&W, as the grip is much better feeling then the large frame Glocks, and its a lot easier to fix the stiff trigger on the S&W the to change the grip feel on the Glock.
