    Anybody know how deep that pocket is on the G18 slide?
    (the lightening cut in front of the rear sight)
    Thanks.

    Yes, C&S, I noticed that in a magazine recently.
    Pretty reasonable too, $100.

    From the top of the firing pin hole to the top of the slide is about .220". So you could probably go .125" deep, or a bit more.

    How does the lightening cut affect function or durability? Do you have to change the recoil spring?

    I read about this in an article on a G17 that Cylinder & Slide modified.
    There is less muzzle flip due to less reciprocating mass.
    Supposedly this is why the G18 has the lightening cuts.
    C&S put in a 19 pound recoil spring, stock is 17lb.

    From what I found, the G18 weighs about 1.26 ounces less than a G17.
    Doesn't seem like that much, but must make a difference.

    Lightening the slide also probably increases the ROF.

    I will have to run PACT IV timer and compare it with a regular G18 to see how the RPM compares. My guess is the lightening cuts were made to offset the reduced blowback from the barrel comp ports.
