I have some OEM Boxes that the fitted foam is disintegrating. I called Sig C/S and they had no solution. Does anybody have this problem? How do you replace the foam? Thanks

I have used Pelican Foam when the factory stuff turns to dust. I use pelican cases, totes, and crates for shipping electronic equipment and their foam is strong, durable, and easy to customize with a jig saw and razor knife. Here is site where we get new foam to convert a case for a different piece of equipment.

I purchased foam sheet from JoAnn Fabric. They had a couple different densities. Go for the highest. I chose 1" thick, easy to put one layer in cut the next and lay it in. The lady at the measuring table pointed out some spray adhesive that allegedly worked well to glue the foam sheets together. I didn't glue anything, might want to change it later.

JoAnn's uses an electric food carving knife, which gave very good cuts. I used one for the big squares but used a steel rule and razor knife for the cut outs.

Thanks, Dave. I've looked at Pelican and I had hoped to buy something premade. It seems like I can't be the only one that has this problem.

Thanks, P35 I'll look into that.

First approach was store Sigs in plastic sealable storage bags in the old Sig boxes with foam, worked ok. Then I purchased about a dozen sheets of S&W VCI paper to replace old worn paper for my vintage S&W revolvers. Thought why not use same paper for the Sigs. Worked better than I hoped, much better fit in foam box for both the Sig pistol and spare mag.

Besides the electric carving knife or exact knife how do you cut this stuff to look professional. I have butchered some pelican cases. For some reason I thought there was a way to like “melt” cut through but I don’t know how.

There are a lot of "pre-perforated" and "pull-and-tear" foam suppliers out there. From my years in the audio and video world, still the best for custom foam fit is an electric knife, steel ruler, and a Sharpie. Custom fit surrounding something always requires two pieces, one cut, one flat, and glued together for the finished product.
