Only produced from 1987-1990. Collaboration between Springfield and Peter Stahls of Germany the Omega was born. The slide was designed by Peter and was assembled by a group of less than 20 of his gunsmiths. He still custom builds handguns today that sell on average of $4000. His slides were married with Springfield a1 lowers. Has unique feature including double extractors, ported barrel and slide built for and around the powerful 10mm. This particular one is an early run that has been keep unfired with original box and cleaning tools. Has lifetime warranty that Springfield still honors to this day. Gunbroker has them ranging from $1700-3000+. Please pm offers and I am able to meet between Calhoun and Ringgold on i75.
