PDI 05 Inner Barrel for Tokyo Marui SIG P226
By Q Project

 

Introduction
In 2005 PDI released the "05 Inner Barrel For Marui Sig Sauer P226" a 6.05mm stainless steel inner barrel for the TM SIG P226 sold under the X-Fire branding. Installing the barrel is easy enough. Basically you take the slide off, take the barrel out, remove the inner barrel & hop-up from the outer barrel, unscrew the 2 screws on the left side of the hop-up unit, pull the left side of the hop-up unit off, remove the OEM barrel and swap the hop-up bucking on to the new barrel. Installation is the reverse of the removal.

    Test Stats
  • Temp: 74' F
  • Range: ~11m
  • Gun: Tokyo Marui SIG P226 GBB
  • Gas Type: Green Gas 265 fps
  • BB Type: Excel .20g

Testing
The test barrel was installed in an otherwise stock TM SIG P226 that had seen a bit of action, but was in pretty good condition. The test was set up at a roughly 11m range shooting at a 14cm square target (similar to the ARMS target used in the original SIG P226 review.) The shooting was done in the sitting supported position, without a vice. The test was originally attempted with HFC 134a gas but the velocity was lower than normal, so green gas was used.

Conclusion
In respect to accuracy, the PDI 05 Inner Barrel is slightly better with the exception of shooting a bit to the right. (Corrected with a bit of "Kentucky Windage" on the 3rd target.) In respect to precision, the PDI 05 does a better job of keeping the shot groupings together. Considering the short length of a pistol barrel (relative to an AEG barrel) it stands to reason that adding a tightbore barrel wouldn't make a huge difference, which is the case with this barrel. In a bit of informal testing the target was a 8x5 inch sign at a range of about 30m. With both barrels the shots were falling short of the target. With a bit of adjustment, hitting the sign was still tough. Perhaps with an upgraded gun the PDI 05 would have more effect.

Final Word:
The PDI 05 Inner Barrel for the TM SIG P226 is an improvement over the stock barrel.
