Applying spec numbers to real life for newb

[DaveInTexas]

I am looking at the Glock website and they list a bunch of specs such as:

-weight
-line of sight
-trigger pull
-trigger travel
-barrel height
etc

For a newb, these specs are hard to apply to real life.

Is there a place that will tell me averages, or normals, or what a certain value means subjectively such as these hypothetical examples:

"Wow, a trigger pull of 6lbs - that would be used for ______ purpose, and the user should expect to be tired after a few dozen rounds"
or
"a barrel length of 150mm - definitely a large gun that would not be suitable for _____ uses and would normally be only seen used for _____"
or
"an all up weight of 0.5kg - extremely light gun, no good as a _____ but would do well as concealed carry"

Thanks

You really need to get to a gun shop and put your hands on various models...reading about them isn't going to do much for you.
You want to try trigger pull...go 'click' a Glock (4-5#) trigger, then pull a S & W revolver (10-12#) trigger...then you'll understand the difference. (Note: Trigger pull involves both distance and pounds...for you to find the one you like.)

What someone else likes may not be your cup of tea...gotta' get to a gun shop and look around.

OK sounds reasonable.
I like to research before I go looking, as much as poss.

+ 1 on what the retsupt99 said.
Also take a trip to a range and rent different gun to shoot and get a good feel for them as well.
