Compatibility
| Brand / Platform | Compatibility Verification | Tuning & Adjustment Notes |
|---|---|---|
| Maruyama SCW-9 (GSeries / Glock-style magazine well) | Direct Native Fit | Purpose-built for the Glock-pattern magazine well and feed geometry used by the SCW-9 GSeries. Seat the adapter fully and confirm a positive seal against the loading nozzle for maximum gas efficiency and consistent feeding, without introducing drag on the reciprocating assembly. |
| Maruyama FMG-9 / SCW-9G / SPC-9G | Direct Native Fit (Shared Glock-Style Magazine) | These share the Glock-pattern magazine well. Fit and tuning are identical — no additional adjustment required. |
| Maruyama SCW-9 (MP9-style magazine well) | NOT Compatible | The MP9-style variant of the SCW-9 uses a KWA MP9-pattern magazine well with different catch geometry. Use our Maruyama SCW-9 adapter for that configuration. |
