     This was the 9x19mm version of the M10 which used the same receiver and was very much identical to the .45 ACP version. After prototypes had been made, Ingram switched from using the 9mm Sten magazine two the very successful Walther MPL magazine. This helped eliminate feeding problems that were notorious with the double-column, single-feed Sten magazine. The 9mm M10 operated exactly the same as the .45 ACP version and also had a 9mm Sionics suppressor intended for use with it. The 9mm caliber extended the appeal of the M10 weapon to other countries that did not stock the .45 ACP round as standard. Also, clandestine services and Special Operations forces preferred the 9x19mm round as being more universally available as well as not being directly attributable to the US Military.
