These work for the Remington r1?

Will work with any 1911 mag with pre drilled base plates

will these fit a micro 380?

These pads were designed for a .45ACP, I doubt they will fit the .380 mag But with a little sanding I think you can make it work.

Will This work ON ruger 1911 9mm magazine?

If the base is drilled it should fit if not yo would have to drill the corresponding holes. I put these on Springfield factory mags and a couple of no name mags I had.

I ordered this item 9 days ago with Prime and it still hasn’t been shipped, is this normal?

No, prime time is 3 days delivery guaranty unless is not prime.

Great deal, fits perfectly

I had 3 spare magazines for my Springfield Garrison that didn’t have slam pads. Springfield get $45 a piece for magazines with slam pads, and these from Kimber fit perfectly! Even the screws are an exact match. They literally took me 10 minutes to install all three. Super happy!

Functional.

I adapted these base pads to fit standard 1911 mags, put them in my drill press, drilled new holes, screwed right on looks great, fits great.
