    'Tuner, thanks for the photos.

    What I'm curious about is a job done properly. The magazine always show the $3000 custom guns with the 150 man-hours invested in it, so of course the ramp is perfect. And you've shown us a couple of botch jobs. But can you show us a Before, During, and After? You know, if you get one in, and the owner consents to have it documented.

    Sure, I'm curious about the procedure, but this is even more to reinforce in me that it's over my head. :p

    If the ramp is perfect, and all is within spec...no procedure is necessary, and could even be detrimental.

    My apologies. I realized late yesterday that I had "gunked up" this thread before reading the volumes of incredibly helpful information already archived elsewhare on this site.

    Stem jams.

    Great, great stuff.

    (Thanks for not :neener: ing me ...)

    Question about a S'field 1911 Hi-Cap

    I have just bought a new Springfield 1911 Hi-Cap. It fires flawlessly with FMJ ammo, but doesn't like the Brass Encased Bullets -- one or two FTF's per 13 round magazine. (I haven't tried JHP's yet.)

    I noticed that the feed ramp is tiny compared to my other 1911's -- all of which are single stacks. In other words, the other feed ramps roughly follow the contours of the top of the mag well, even my Springer WWII GI. The high cap's feed ramp is a tiny little inverted triangle, maybe .25 inch wide at the top. My question is, Would a feed ramp job by a capable gunsmith be of any benefit? Or is the feed ramp designed this way because it's the only thing that will work with Springfield's double stack mag? Thanks.

    Yup, ya' got a real clue there. And no, a double-column magazine doesn't feed exactly the same way a single-column one does.

    If it functions reliably now, don't mess with it.

    It is not uncommon at all for the feed ramp to be smaller looking in a high cap than a single stack.

    For one thing, the mag well is a lot wider, so even the correct sized cut looks smaller.

    For another, the double stack mags I've dealt with (mostly STI/SVI 2011 stuff) present the round higher in relation to the frame than the single stack guns do, so they can get by with a shallower (and thusly narrower) ramp.

    That said, just last week I had to re-cut the ramp on an STI 2011 frame because it was so shallow that the thing wouldn't even feed 230 grn ball (FMJ RN).

    If it runs now without issue, don't futz with it and create an issue.

    That's my stance.

    When gunsmithing, you gotta be like a doctor, always remember: "First, do no harm."
