Trigger Pull: The Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol has a single and double action trigger setup. Both feel pretty good with a surprisingly light double action trigger pull, the blowback action will cock the hammer between shots allowing for the vast majority of your shots being single action which you will find are short and very light. There is a little bit of take-up followed by a crisp light release.

Accuracy: So far I have not made my Field Test Shooting Video for the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol. Keep posted for my upcoming Field Test Shooting Video for the Cybergun FN Herstal FNX-45 Threaded Barrel GBB Airsoft Pistol, until then I can not really comment on the shooting results.

Build Quality: The build quality of the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol feels really good, it has a nice weight to it and feels really solid in the hand. The materials used look good and have an excellent finish to them. There is just a bit of a slide wiggle but not excessive. You will find metal parts where you would expect them to be like in the slide, barrel components, magazine, slide catch release, take-down leaver, hammer and lots of internal parts.

Realism: In terms of realism the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is pretty much the spitting image of the real steel version with all the markings and licensing in all the right places. Mechanically everything works about the same including full field strip-ability with full ambidextrous controls.

  • Just a little bit of slide wiggle.

The Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is a really great looking gun. The quality is on par with KWA and KJ Works in my opinion. I’m not sure who actually makes it as Cybergun is the license holder and distributer but I feel like the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol is a step up from the standard KWC gun often used as the base. I look forward to testing out the Cybergun FN Herstal FNX-45 Tactical GBB Airsoft Pistol in the Sea Can indoor Airgun Shooting range to see how it performs. I’ll be testing with the short barrel and with the barrel extension installed to see what the fps difference is between the two.
