Take Your Single Stack Build to the Next Level with the NQI PFSS Front Locking Block
The NQI PFSS Front Locking Block is designed to take your PF9SS G43 single stack builds to the max. Made from American 17-4 stainless steel and precision CNC milled, this locking block is stronger, tighter and will last longer than MIM or stamped parts.
Unlike heat treated parts that can wear out your slide, our non-heat treated design allows the rail to wear before your slide does — protecting your investment over time. The tighter tolerances will improve overall accuracy making this a must have for anyone serious about their single stack builds.
For builders who want perfection, some final honing can get you an ultra flat rail system from front to rear but it’s not necessary for most applications. Check out our videos under the manuals section to see advanced techniques to get you closer to a match grade finish.
