A great 45 auto but... it jambs at times with any mag and any load.
I have been told the ramp needs to be polished etc. Has anyone here
done this themselves? I have not found a mechanical task that I can't
perform. Heck I might try brain surgery if I could find a patient.
Seriously I am thinking Dremel tool and polishing compound. I have
googled the task but would appreciate other experiences.
Thanks
Kenneth

I've polished many feed ramps...but never on a handgun that was a
problematic as yours.
I used the felt polishing wheel and jewelers rouge.

I have never done it; but I have friend, who is a dentist, and he used his
dental tools to polish the feed ramp.

When I wanted to feed semi-wadcutters in my Springfield 1911A1 Factory Comp
model I sent it to Springfield. That way if it got screwed up it would have
been Springfield's responsibility!

"Told " by who? It could well be a rough feed ramp, but I doubt it. How is
it jamming? Normally a 1911 that will not feed is a simple fix, but if you
don't know what you are doing attacking it with a dremel tool will seldom
fix anything, and may well make things worse. If you don't know the safest
thing to do is take it to a REAL Gun Smith. You need to be careful here,
many people who have an FFL to sell guns, think it made them a smith. Find
someone who actually works on / builds guns. If you can find one locally
chances are they can easily fix it so it feeds anything, and it will not be
expensive. Start trying to do it yourself not knowing exactly what you are
doing, and the repair bill could soon be as much as a new gun.
If you can't find a Smith in your area invest in a good book on the 1911. It
will show you how they are supposed to work, and may show you how to fix it
yourself the right way.

Any work with loose polishing compond and a power tool will get grit
everywhere, including into the sear, trigger and disconnector. Been
there done that, even when masking everything off. Try some rubber
Craytex (sp) cones for the Dremel instead. It's still better to
completely disassemble the frame and thorughly wash it afterwords.
Exactly what kind of jam are you getting? Failure to feed? Failure to
extract? Double feed?

Look at the Blindhogg site for lots of 1911 how-tos by a 1911 gunsmith.
Better yet, buy the Khunhausen books. they are the de facto shop manual
for that pistol.

Kenneth,
A dremel might be just a bit of overkill, depending on what you have to
begin with.
If it isn't too rough and the toolmarks do not show, you might be better
served by a short length of 3/8" wooden dowel, wrapped with a strip of 600
wet-or-dry. Make longitudinal strokes, in the direction of the cartridge
travel, in preference to rotary. I'm sure you will appreciate that direction
as you consider leaving more marks to either drag the bullet or funnel it
along.
Most modern factory barrels need only light polishing on the ramp and the
merest of deburring around the mouth of the chamber, to prevent the bullet
dragging there.
Go a little bit at a time, and you will be surprised with the reward from
merely polishing.

I would stay away from the Dremmel tool. It is much too easy to take
off too much metal. I've polished feed ramps simply with a piece of
wooden dowel and progressively finer grades of emery paper. You just
want to get rid of any obvious burrs, etc. I've done a Makarov and a
Browning Buck Mark this way.

Jambs trying to load (about half way up) which makes me think of the
ramp. The scrapes are clearly visible on the ramp and it is rough
(like a casting that has never been ground.
Understand about disassemble and washing. Will look into the Craytex.
This has been with FMJ ball ammo/HP as well.
Thanks
Kenneth

That is a good idea and more controlable than a dremel tool!

I just saw another suggestion for this approach and think it is a
great idea. Glad to have a confirmation from you w/link.
Thanks

Power hand grinders are the LAST resort, hand polishing is to be
preferred. If you gotta, use Cratex rubber-bonded points and clean
well afterwards before use. You can Dremel your way through some
expensive parts if you don't know EXACTLY what needs attention.
Again, you need to tell us what KIND of jam are you getting, feed ramp
polishing really only helps in certain instances. Could be extractor,
could be ejector, could be a rough slide face, over-powered recoil
spring, rough chamber. Could even be a dud mag catch. Need more
description of what exactly jams up. Is the case partly extracted, is
it trying to feed one with another still hooked to the extractor, is
it the classic stovepipe? Or do you get "Bang", "Click" with the
expended case stuck in the chamber? Lots of ways to jam up, lots of
other things to do other than polish the feed ramp.

If it won't relably feed hardball maybe you should turn it over to a
gunsmith. My Remington Rand 1911A1 Feeds semi-wadcutters relaibly, it
doesn't appear to have beeen modified..
