Airsoft Masterpiece
Code: STS-4G
  • Steel replacement safety catches
  • For TM Hi-capa and clones
  • Extended design for fast access

As far as Hi-capa parts go, there aren't many better options than those made by Airsoft Masterpiece. The Steel Thumb Safety Type 4 replaces your original safety catches on either side with a precisely machined part made from steel, with extended contact surfaces allowing you to take the safety off in an instant!

Full description


The Steel Thumb Safety Type 4 is intended to replace the stock safety catches on a Tokyo Marui Hi-capa GBB pistol or clone, and provides extended control surfaces for fast access. Each catch has linear checkering machined in, to ensure you get the prerequisite grip when operating this control. This part would be ideal for a Hi-capa race gun setup for competition shooting, as these competitions often mandate the safety being engaged before the draw. With the Type 4 levers installed, the surface you have to hit to release the safety nearly doubles, saving you precious fractions of a second on the clock, which could make the difference! The right side safety catch is also extended but by slightly less due to the lack of other controls on the right side meaning there is little to inhibit a left-handed shooter from drawing and removing the safety quickly.

The Type 4 safety catches are made from steel, and finished in a hard-wearing metallic gold coating; very fitting for a race pistol! The steel construction absolutely eliminates the possibility of your safety failing during a comp, costing you time you simply don't have to spare.

Parts Fitting

Upgrades and Downgrades should only be undertaken by experienced players, or Airsoft Technicians. Please note, changing any internal parts of a weapon voids its warranty unless done in-house by our staff. 

Please ensure that when fitting parts the part purchased is the correct part, as once a part has been fitted we cannot accept return.

We do know that players love to tinker, so we're here to give you help should you require it, and if needed you can get in touch with our workshop for more help!

Unique Parts

Please note that some parts may be unique to a specific brand of weapon. For example: Parts for an ASG M4A1 may not fit an ICS M4A1.

Parts from the same brand typically have a high chance of fitting, though be warned, some replicas use unique parts, so please ensure the part will fit before you attempt to fit it.
