Affordable starter lpk - Polymer80 PF-Series Pistol Frame Parts Kit With Trigger Compatible

This LPK is good for completing any of your PF940 series(full, compact, and sub-compact). You can then run it and make sure you are good to go before upgrading other internal parts. 3 Slide lock springs(full, compact, and sub-compact) and 2 trigger profiles(flat and curved). Polymer80 does have a decent quality and I trust them for my own use.
