The 1911 world is full of single stack auto loaders chambered for the 10MM Auto cartridge. Most 1911s are 5" or longer to take advantage of the 10MM Auto loadings
The SIG P220 is only offered in a 5" barrel and only on the steel frame. The HK in the photo is a double stack
There are lots of pistols that have been converted to 10MM Auto over the years. The Smith and Wessons are probably the best for a conversion. These make great carry guns because of their alluminium frames
