    So I'm a pretty qualified machinist and I want to mill the top of my xd 4in.... The area just behind the front sight...

    There is a small pocket milled on the inside of the slide, above the barrel and there's slides a serial number stamped in it.

    I'm thinking of milling two parallel slots on both sides of the serial...

    Anybody got any advise or has anybody got pictures of there milled slide I can use for reference

    Perhaps I'm missing something here. Just what would be the purpose of "milling" the slide in such a manner?

    Mostly just for show but actual purpose being ventilation
    Also thinking of get a stainless ported barrel

    Yea I forgot to ask if that serial is important cause its not the guns registered serial number

    I've seen someone did it to a xd 5in but I'm not sure if it has that number in the same spot cause he milled the whole area out... Area that I am referring to

    If I understand what you're wanting to do -

    It's called "lightening" the slide.

    It's done to longer slide / barrel auto's to help the slide cycle faster.

    It's being offered from the factory by XDm - Glock - S&W - Sig and I'm sure others that I haven't heard of.

    Here's my Sig P220

    Here's my XDm 5.25" - it has been lightened, but this picture angle doesn't show it well

    It seems to work as more & more manufactureres are offering it.

    I just like the looks.

    I hope this helps.

    :cool:

    yea thats the idea but two on top of the slide

    you thimk doing it to a 4in is a bad idea?

    I had a gun "Ported" to see if I liked it.

    Plus holes in barrel to match.

    I do not like it at all.

    Large flash comes out of the top of the slide - blinding at night & in low light.

    I wouldn't suggest putting them on top -

    I believe if the ports were on the side it would still be blinding

    JMHO

    :cool:

    Those are some massive holes in that slide... I hope the ports in the barrel aren't that big and if they're matching up the muzzle flash is going to go straight up and in your sight line

    If there's two Slots side by side two most of the flash would dissipate in the slide... Or so I would assume

    I don't think it would matter if you milled the number out of the slide.
    I believe it is there to keep the parts together during manufacturing.

    Just don't mill it off the frame:D

    I've ported a few guns on an EDM machine, like Mag-na-Port does. I always angled them to the side and the flash isn't bad. I haven't done it in a few years, no more access to the EDM.

    Just a thought to the op, the recoil spring weight is typically tuned to the mass of the slide so be prepared to possibly have to start changing springs and/or loads to correct the gun's timing.
    It might also make your gun more load sensitive and less reliable over a broad spectrum of ammo types. This of course depends on how much mass you remove.
