0940 and 1045 Receivers, What's the difference?

Angstadt Arms offers two different lower receivers the 0940 and the 1045. Both lower receivers are designed around using many mil-spec components including safeties, fire control groups, takedown pins and grips. The receivers are also designed to use as little proprietary parts as possible.

The 0940 receiver is designed to accept factory Glock magazines in 9mm, .40 S&W and .357 Sig. 

The 1045 is our large frame receiver and is designed to accept factory Glock magazines in .45 ACP and 10mm.
