    Did I cut the barrel ramp too deep?

    This is my first 1911 build. It is a 9mm Kart barrel. Just want to know if there is too much brass exposed and if the experts think it is safe to fire?

    I am no gunsmith, but I do not think that looks promising. I would also be concerned about the angle of the feed ramp.

    Hmmm....

    +1 on the feed ramp.

    Heres what it should look like. I would not attemp to shoot your barrel.




    There are only three types: Trained, Un-trained or JAFO.
    Which one are you?

    Anyone have pictures of a 9mm barrel? The angle is fine, it feeds dummy rounds very smoothly. I just need to know if it's gonna blow a case out if I fire it.

    The amount of exposed case is the same on the 9mm as it is on the 45. All you have now is a paperweight.

    First, that isn't a ramp it is a relief. Second, didn't the barrel come with the relief already cut?

    In short, NO! Please step away from the dremel tool!

    I don't know about a 9mm, but on a .45 barrel, .090" is generally considered the maximum allowable exposed cartridge sidewall, measured from the cartridge groove ramp/case wall intersection.

    Kart barrels come ready to install except for minor fitting to insure lockup. no need to touch the feed ramp or relief.

    Is it ground offset to the left?
