You often see expanded capacity magazines around.
In the past they've been made for many guns, including the 1911, Walther P-38, Browning, Glock and others.
"Usually" these are made by no-name companies of substandard materials, and very often fail to work well.
Part of this is the inability of the gun to operate with the super strong spring needed to lift the heavy column of cartridges, and a large part is the usually crappy manufacture and materials.
In short, these are very much hit or miss, usually miss.
