This case said "small" on the packaging. I don't know if it comes in any other sizes. This one fits my HK45 perfectly with just a tad room to spare (about 1/4 inch). It does also hold one spare mag which is nice. I recommend this product. The only thing I would like to see is a list of some of the popular handguns it can contain. My full-size handgun fit perfectly with virtually no room to spare but other full-size autos might not.
