Lately, the MasterPiece Arms catalog includes Ingram-style semi-automatic pistols and carbines in 9mm.

For the Ingram M-10/M-11 platform, however, these inconvenients are now history: MasterPiece Arms itself redesigned the trigger and locking systems of its MACs so that they would ensure flawless operation. The earlier semi-automatic MAC-10 versions were known to be quite unreliable, just like many other semi-automatic, civilian-grade versions of open-bolt sub-machine guns: the conversion of the working system from the open bolt to the closed bolt − which is necessary to make them civilian-legal in the United States − normally causes a bad timing and makes them prone to repeated stoppages. Semi-automatic versions of the MAC-10 platform − redesigned and manufactured so that they could not be converted to full-auomatic fire − provide good solidity and excellent firepower, which still makes them very popular in the United States between sports shooters and gun collectors. Its manufacturing and marketing history was somehow turbulent, but showing up in a number of movies, TV series and other entertainment products in the past 40 years turned it into an icon of the guns world, much like the M-16 or the AKM. The compact sub-machinegun engineered by Gordon Bailey Ingram between the 1950s and the 1960s has since been one of the world's most famous hand-held automatic weapons. That is, given that the Company − headquartered in the town of Carrollton, in he State of Georgia − is America's (and possibly the world's) premier manufacturer of semi-automatic firearms based on the well known Ingram M-10/M-11 platform − popularly known more simply as the MAC-10.

The name of the MasterPiece Arms Company is not known to many shooters and gun owners outside of the United States, unless they're really 'into' the American gunmaking sector.
