FK Brno Factory PSD 9mm Caliber Conversion Kit - 5.3" Match Grade Barrel, Matte Black Nitride - Includes Two 9mm Magazines & Recoil Tuning Spring - FK-PSD9-KIT
Product Description
If you love running the proprietary, hyper-velocity 7.5 FK bottleneck round out of your premium FK Brno PSD handgun, you know that high ammunition costs and restricted range availability can limit your training cycles. Feeding a steady diet of exotic 7.5mm defense cartridges is a significant investment on any staging bench. The **FK Brno Factory PSD 9mm Conversion Barrel Kit (FK-PSD9-KIT)** completely flatlines this problem. It allows your polymer multi-caliber sidearm to switch seamlessly to universally accessible, low-cost **9mm Luger (9x19mm)** ammunition in less than a minute.
Proudly engineered and manufactured to world-class Czech standards, this factory performance package features a full-length **5.3-inch match-grade conversion barrel**. Cut from premium ordnance-grade steel billet and treated with a friction-reducing, matte black nitride armor shell, the barrel matches the proprietary lockup timing of the PSD slide perfectly. Because standard 9mm ammunition operates at lower pressure thresholds than the massive 7.5 FK cartridge, the kit arrives bundle-completed with a factory-calibrated, lighter tension recoil tuning spring to ensure flawless extraction tracking and smooth slide cycling.
The kit is completed with **two factory-original 9mm magazines** featuring optimized internal geometric channels to stack and present the straight-walled 9x19mm column directly past the feed ramp. It is the ultimate asset for expanding your training capabilities right on your armorer workbench.
*Armorer Bench Notes & Real-World Staging Guidance: The FK Brno FK-PSD9-KIT conversion assembly arrives secure and grease-preserved inside a rigid factory presentation container. EXCLUSIVITY AND HOST COMPATIBILITY MATRIX: This conversion layout is custom-profiled strictly to drop into the **FK Brno PSD (Polymer Sport Defense) multi-caliber pistol frame**. It will not fit legacy all-steel Field Pistol variants due to separate internal frame footprints. Armorer Workbench Caliber Conversion Sequence: 1. Completely verify your PSD is unloaded, magazine removed, and clear of live ammunition. 2. Field strip the slide block off your frame. 3. Compress and remove the heavy 7.5 FK factory guide rod and recoil spring layout. 4. Lift out the 7.5 FK factory barrel. 5. Drop the new 5.3-inch 9mm nitride match barrel directly into the slide pocket. 6. Swap your active recoil spring on the guide rod for the included, lighter 9mm tuning spring. 7. Reassemble the slide onto the receiver and rack the action by hand several times to verify smooth mechanical timing. Magazine Staging Precaution: To achieve absolute feeding reliability with 9x19mm cartridges downrange, you must use the two dedicated 9mm magazines included in this box. While the PSD's multi-caliber steel magazines can technically accept 9mm rounds on your staging bench, their feed lip geometry is loose-calibrated for wider casing blocks. Staging the dedicated 9mm magazines prevents double-feed orientation failures during intensive training loops.*
