So, you decided to take a perfectly good working gun and alter it? Why? Did you have some feeding problem?

I think the 500 grit is a little coarse for polishing.

Using flitz or jewelers rouge is one thing, but 500 grit sand paper is a bit much in my opinion.

I polish the feed ramps on all my guns. Is it necessary? Probably not, but it's one less thing I have to worry about causing problems, and makes cleaning easier.

Back in the day , up until aprox mid '80s , it was pretty much a given that every bottomfeeder ( or jamamatic as they were know back then) needed some attention to be reliable with anything other than fmj , and sometimes for that also. If it required *only* feed ramp polishing , you were coming out lucky.

Fast foreward to early '90s to date. The expectation is for bottom feeders to be reliable with the vast majority of , if not all factory ammo and quality handloads. In the modern times clean , lube , and possably a break in period. Nothing else done or contemplated , unless actual problems persisting after a reasonable break in period.

And POLISHING meant jewlers roughe , crocous cloth , and similar. With 500grit sandpaper you're doing a mild throating.

Slightly off topic , but to me the most revolutionary thing about Glock 17 wasn't the plastic construction , or the fire control system. It was the fact that they actually worked , and feed every type of ammunition out of the box w/o any further gunsmithing. This quickly created a customer expectation of new guns to actually work, and every other mfg had to scramble on QC and design tweeking to compete.

I polished my feed ramp on my shield 9mm. I used the dremel polishing compound and Flitz polish. But I used elbow grease and rubbed and rubbed until it was the way i liked it. No sandpaper or dremel used.

For one I don't remember saying I wasn't having feeding problems and I am a machinist by trade so I think I know a little about metal the 500 grit wet/ dry sandpaper along with a good gun oil will take very little metal off it mainly works the oil into the pores of the metal so read the post before you express your opinion please

OK then, let me jog your memory:

To me, when a person says "no problems whatsoever" it means they haven't had any problems. Feeding problems are problems so you can see why we thought you didn't have any trouble with the gun by what you said in the OP.


Please don't take our comments the wrong way. They are just opinions on the internet. I'm glad you enjoy your gun, I like my M&Ps too. I'm just of the opinion that if it's working good, don't adjust it. If you want to adjust your gun, by all means have at it. Just remember that many others here don't have the experience you do with metal. Suggesting that particular grit could lead them to damage their pistols because they don't have your experience.

I agree! Why polish the feed ramp if the weapon was firing just fine. If you were having feed problems, I could possibly see possibly polishing the feed ramp. But you could cause more harm if you took off to much material. The feed ramp is designed to a certain tolerance.
