My KWA M1911 won't fire when I pull the trigger

If you've properly loaded the magazine with gas and there's no movement or noise when you pull the trigger, other than the hammer dropping, you're likely missing your firing pin. This only happens when the item is dry-fired, which is why we advise against dry-firing in the instruction manual. To see if you need to reinstall a firing pin on your KWA 1911, watch this KWA Maintenance Minute:

If you do find that your firing pin is missing, search the KWA Store for the D-53 firing pin, which is seen as part 60 on M1911 diagrams.
