Polymer 80 INC PF9SSBLK: Polymer80 is pleased to present the PF9SS 80% Subcompact Single Stack Frame. Offering compatibility with Glock 43 Gen 4 components, the PF9SS frame comes with an aggressive texture that emulates a stippled pattern, an extended beavertail, a double undercut trigger guard, and a thumb ledge.
