Tried A Little Feed Ramp Polishing...

[AnthemBassMan]

-Well, I couldn't leave well enough alone. The feed ramp wasn't really rough, just the same matte color as the rest of the barrel. So I got my Dremel, a felt cone polishing tip, and a bit of polishing rouge. Cleaned up nicely in just a few minutes. It really has a mirror shine to it now. I kept the Dremel on low speed and used light pressure to make sure I didn't do any damage. Not sure if you can tell by the pics. I used my phone which barely passes as a phone...

thats how i did it. i used some steel polishing compound and a dremel on low speed

bio...quick question.
After 20-30 rounds (and I did not polish any internals at all, including the ramp) my ramp gets a little dirty. On your rig, does the ramp stay cleaner longer...or does it get fouled just as easily?

When I had a Sigma I polished the feed ramp just using a piece of coarse typing paper rolled around small dowel that had about the same radius as the ramp & used a little elbow grease. I had noticed the matte finish & non-shiny surface the first time I field stripped the gun & declared it not cool. I was reluctant to use any abrasives or power tools & I found that it was unnecessary. It didn't take long at all to get it to a mirror shine. A friend who also has a Sigma used toothpaste as an abrasive & it worked equally as good in about half the time it took me. Neither he or I ever had a feed problem with any ammo we used. Since we both did the polish job before a shot was fired through the barrel there's no way of telling if there was a problem in the first place.

I noticed that both my FS M&P40 & 40C came out of the box with highly polished feed ramps. Is that an omission by S&W on the Sigma?

probably done to keep the SD/sigma price down

Typing paper? Really? Seems like that wouldn't be very abrasive at all. I've seen videos and read posts where people used Flitz and Q-Tips...I feel more comfortable trying that, than I would a dremel. I tend to get carried away with power tools.

Plus it has minty fresh "breath."

-Yep, that what I'd say. Another cost cutting measure. Doesn't bug me none. If I can save a few $$ and do something like that myself, I'll do it. Here's a pic of the gun back together. You can definitely see the polishing job in this pic. I was thinking about polishing the outside of the barrel too, but I think I'll just leave that alone for now...

My shield 9 looked good right out of the box.

its a M&P different series of hand gun. SD is the value line. corners are cut but easy to overcome by ones self

I polish ALL my semi feed ramps.

You can HEAR the difference.

Turns a ka-chunk, into a quick "snick", when feeding.

Time well spent in my opinion. When time is a factor (ie a quick field cleaning) it seems like polished feed ramps clean up much quicker than unpolished. Same same for extended shooting sessions. A few seconds with a dry tooth brush (I use my wife's lol) is all it takes....

My experience is that the fouling doesn't latch on as easily but it will after enough rounds. But it wipes off much easier.

After my next range session when I take her down to clean her I'll give this a shot. Not so interested in internal cosmetics but if it keeps it cleaner and improves operation somewhat, I'm interested.
