Real 2025 Builder Reviews “Built a 10mm woods gun — the grip texture + undercut makes it feel like a completely different animal than a stock G20.” – Ryan M., Alaska “FDE kit came out perfect. Reinforced jig didn’t flex once on the deeper cuts.” – Chris T., Texas “Finished in 78 minutes. Dropped in a Lone Wolf slide — shoots softer than my Gen5 G21.” – Sarah K., Idaho
Frequently Asked Questions Q: Does it work with Gen4 or Gen5 large-frame slides? A: No — Gen3 only (tons of aftermarket Gen3 slides available).
Q: Will factory Glock 20/21 magazines work? A: 100% drop-free.
Q: Can I use a regular Easy Jig Gen 3? A: It works, but the dedicated PF45 jig is stiffer and faster.
