Learn what the IFYKYK back plate is, which Glock and Sig models it fits, and follow a safe step-by-step install with checkpoints to avoid common mistakes.
Quick answer
The IFYKYK back plate is a cosmetic slide cover plate that swaps in place of your factory rear plate. Installation takes about five minutes with a punch or small flat tool, but the critical step is compressing the striker spring before you slide the new plate on.
What the IFYKYK plate actually changes
This is a rear slide cover plate, not a performance part. It replaces the flat factory plate on compatible double-stack and single-stack Glocks and Sig M17/M18 pistols, adding a custom look without altering how the striker or trigger safety functions. Because it is a pre-order item with a stated lead time of two or more weeks, plan the install around that delivery window rather than a same-week match or class.
Fit boundaries and why they matter
The catalog lists compatibility for double-stack Glocks Gen 3-5, Gen 6 double-stack Glocks, Sig M17/M18, and single-stack Glocks such as the G48 and G43X. That covers many popular carry guns, but it does not list every model. If your pistol is not named, treat fit as unconfirmed rather than assuming a similar-sounding model will work. The plate is also not described as an extended or optic-related part, so do not buy it expecting extra clearance or added function.
Step-by-step IFYKYK back plate installation
- Unload and verify: Remove the magazine, lock the slide back, and visually and physically confirm the chamber is empty before any disassembly. A safe install starts with an empty chamber, not a loaded one.
- Remove the slide from the frame: On Glocks, pull the slide back slightly, pull down the takedown levers, and push the slide forward off the frame. On the Sig M17/M18, follow the model-specific takedown procedure rather than forcing Glock steps. If the slide does not release easily, stop and recheck the takedown lever position instead of prying.
- Compress the striker spring and remove the factory plate: Push the striker spring cup forward with a punch or small flat tool while sliding the factory back plate down and off. Work on a clean bench so the spring cup and plate do not launch. Keep a finger over the spring cup during removal; it is the part most often lost.
- Seat the new IFYKYK plate: Align the new plate with the slide channel and press it in while keeping the striker spring compressed. It should sit flush and not require excessive force. If the plate binds, remove it and check alignment rather than tapping it with a hammer.
- Reassemble and function-check: Reinstall the slide on the frame, cycle the action several times, and confirm the striker moves freely and the plate stays seated. Do a final safety check before loading. A plate that shifts during cycling is not fully seated; repeat the seating step.
