College Republican. You are looking at two VERY different pistols.
In common:
Semi-auto
relatively hi-cap
9mm
Different:
One is striker fired, one is DA/SA
One is a higher priced, highly regarded pistol. The other is an "economy" knock off of a fine european gun. (albeit, a generally well made knock off)
One is significantly larger than the other (the 92 being larger).
One is plastic and the other is metal.
If you want a better comparison, look to compare a Beretta 92fs with a CZ75, baby eagle, Ruger P89, S&W 5906, etc...
And compare the Glock with the S&W M&P9, Springfield Armory XD, Sigpro, Ruger SR9, etc...
But you really need to decide what features you are looking for first. Have you shot either of them? It really might help you decide for yourself.
