45 ACP magazine feed lips

[buckaroo45]

I've just spent some 2 hours trying to find the correct dimension between 1911 45 ACP feed lips. Searched every description I can think of both here and Google with nothing difinitive. I thought I saw .380-.385 some place but my 47D's run .383 - .390. I suspect it's here someplace but I just don't have the right search string. I'll bet somebody here knows either the dimension or the search string. At this point I'll take either one.

Here's a great thread on mags.

Great info, amp mangum and thanks to all for the input. I also got input from CMC via a buddy that said adjusting feed lips is a case of diminishing return on effort. Harder metals such as our mags are made of succumb to fatigue over repeated bending. Only makes sense. CMC also pointed out a factor I hadn't considered. Again relative to our style of shooting - slamming a loaded mag into a gun in slide lock leaves only the mag feed lips to retain the combined weight of 8+ rounds. Hell, I'd probably bend too. I try not to get to slide lock but at 64 years old, in the heat of a stage, I miss and or lose count and I NEVER think of babying a mag to seat it.

Set them to ~.420.

The link to the mag info, IMHO, is not very helpful and not correct in the dimensions.

As to leaving mags loaded making the feed lips spread ..... got a chuckle for sure... Any modern mag (read not peanut butter cheapo) will NEVER spread from spring pressure alone....

Hello: I set them to 0.396". That way I can use them for my 40 as well Thanks, Eric

Well... I hope you don't leave them loaded and let the lips swell out and crack the tubes.......

If you want to go the max width I would suggest that you open them up a bit at a time and see how the follower fits. Going to the max will result in some followers trying to come out the top.
