Description
The Franklin Armory G-S223 takes Franklin's patented Binary Firing System and drops it right onto the Glock 22 Gen3 platform. This is a full slide and trigger package, so you get the machined slide, the built-in selector paddle, and the two-position trigger pack all in one box. Set it to Position 1 for regular semi-auto that fires one round per pull, or flip it to Position 2 for Binary mode, where you get one shot on the pull and a second on the release. That second shot is what shrinks your split times and helps tighten up controlled pairs on the range.
What the G-S223 Brings to Your .40 Cal Glock
The slide comes optics-ready, though the adapter plates are sold separately and Franklin recommends sticking with their own plates for proper fit. You also get front and rear tritium night sights for low-light shooting, high-tactile serrations front and rear for a solid grip when you rack it, and anti-glare stripe serrations across the top to cut down on sun bounce. It's a genuinely well-featured slide before you even get to the binary part.
Staying in Control With the G-S223 Binary Kit
One of the smartest touches here is the integrated back plate mode indicator, so you always know which mode you're in without pulling off target. There's also a built-in safety net a lot of folks appreciate: if you're in Binary mode and decide you don't want that release round to fire, just move the selector back to semi while the trigger is still held down and the second shot cancels out. It's a simple, mechanical way to keep full control of what leaves the muzzle.
Keep in mind this kit covers the slide, selector, and trigger only. You'll supply your own Gen3 G22 frame, barrel, and recoil system to complete the build, which makes it a great match for those affordable used or trade-in .40 caliber Glocks floating around. Because of what it is, Franklin strongly recommends installation by a professional gunsmith or a Franklin Armory Certified Armorer, followed by proper training before you run it. Regular cleaning and fresh lube around every 500 rounds will keep it running the way it should.

Frequently Asked Questions
What do I need to supply to complete the G-S223 build?
The G-S223 kit includes the slide, selector, and trigger pack, but not everything to make a working pistol. You'll need to provide your own Glock 22 Gen3 frame, barrel, and recoil system. That setup makes it a natural fit for used or trade-in .40 caliber Glock 22 pistols you may already have on hand.
How does Binary mode work on the Franklin Armory G-S223?
In semi mode the trigger fires one round per pull like a normal Glock. Flip the selector to Binary and it fires one round when you pull the trigger and a second round when you release it. This helps reduce split times and can tighten up your groupings when running controlled pairs.
Can I cancel the second shot in Binary mode?
Yes, and it's one of the smarter features on this kit. If you're holding the trigger back in Binary mode and decide you don't want the release round to fire, just move the selector back to semi before you let off the trigger and that second shot is cancelled. The back plate mode indicator also lets you confirm your mode without coming off target.
Is the G-S223 slide optics-ready?
It is, though the adapter plates are sold separately. Franklin Armory notes that other companies' optics plates may not work properly with their system, so you'll want to run their plates for the best fit. Franklin also recommends having the kit installed by a professional gunsmith or a Franklin Armory Certified Armorer.
