Mr.Hobby Procon Boy WA – .3mm Trigger Type Airbrush


Japanese products were and probably always will be a synonym for quality and reliability. That goes all the way for the scale modeling industry as a whole and of course, for their tools. More than once, I have tested and reviewed different airbrushes made in Japan and they all showed superb qualities and great engineering. My main airbrushes are various, but I have Japanese made among them and when it comes down to get one, I almost always recommend similar items.

Pistols grips are especially pleasant to work with according to my taste. In this review I will want to share with you a pistol grip airbrush that comes from Japan, but it does not fit into the frame well known. It is similar in appearance but only at first glance. Once in your hand, things change.


Mr.Hobby Procon Boy series that I have tested and use were all similar in packing. This one – Double Action Trigger Type – is not any different. We get the standard shelf-friendly packing, suitable for store hanging, with a transparent top. That shows partially the airbrush inside, grabbing your attention immediately and also features some limited information about the tool itself.

On the back of the box, we have a profile of the airbrush with more thorough, but again modest description of the tool, plus a picture of a hand holding it. That gives a hint about the size we will discuss a bit further down.

Opening the pack, the standard plastic box with transparent top and foaming insulation is what we get. It looks simple and more casual, especially compared with Iwata, Sparmax or Harder & Steenbeck boxes.


The foaming holds a wrench, a transition valve for Mr.Air can supply, the airbrush cup and the Mr.Hobby WA PS-275 itself. Beneath that, we can find a hose, suitable for the transition valve and behind the whole box itself, there are instruction sheets.

There are two of them, one only in Japanese, but with a lot of illustrations which are pretty self-explanatory, while the other – more standard looking one. On the latter one, simple introduction to airbrushing is featured plus some troubleshooting and everything that you might want to know when using this PS-275 from Mr.Hobby.

Both of the sheets are useful, even for experienced modelers and airbrush users, so if you have plans to get this airbrush, allow me to give you an advice – don’t avoid them easily, the information is beneficial.


The first moment I got that airbrush in my hand, I was surprised. And I have to say, it wasn’t a pleasant surprise. It seemed too small. But that was only for a little while. It took me few moments to comprehend the idea behind this PS-275 Pistol Airbrush.

It isn’t the standard pistol grip that you can get. Mr.Hobby is smaller and does not feature the usual handle. It is shorter, lighter and even the trigger is smaller compared to GP series from Sparmax or Iwata TR series. And that is where its charm lies.

On the other hand, everything about the tool is pretty standard. The engravings on the side are typical for Mr.Hobby, it says JAPAN, it features polished looks and the needle cap is standard. The size corresponds to a standard /or I have to say – conventional/ airbrush, but it isn’t one. The trigger makes all the difference. So it is a bit of controversial product in general. And I love stuff like that!

It sits in your hand pretty comfortably and it is like you transformed your standard airbrush into a pistol grip but without expanding it. That is strange, but everything comes into place once you start using it. A moisture trap might be helpful if you want to fill your palm with additional piece to improve the grip, but in my case that was unnecessary.

There is a tail stopper, the trigger is smooth along the whole movement range and the color cup is removable. The cup itself screws in into a bed which is part of the airbrush body and that bed itself can handle enough paint so you can complete a basic and short spray session. Pretty much – everything that you might wanna get from an airbrush.


Trying out the PS-275 was – of course – the most important part before I can summarize and write this review. Whatever the basic description of the tool is, how it looks, how it sits in your hand etc., everything comes down to the way it works. And PS-275 works pretty darn well!

The smooth and fine action of the trigger is the key to that. Fine lines are easy and straight-forward with the medium range nozzle size of .3mm. That would’ve been harder with conventional tool. However, the nozzle size is utilized in the best possible way here. It would be better if crown cap is put in the place of the standard needle cap, but as we all know removing the front protection is usually the most common way to deal with this. In this case though, spraying with bare needle is somewhat justified due to the better grip of the pistol type.

Covering larger areas is doable with the same amount of success. Business end of .3mm is wide enough aperture and the color cup is big enough to hold a highly diluted varnish layer for a huge 24th scale airplane or a ship in similar size. The tail stopper adds to that experience, although the trigger itself provides enough control. Overall – pretty wide range of action is possible here.

Size and weight

Mr.Hobby PS-275 weights 128 grams with the lid and the color cup included. If you remove those and use only the bed within the airbrush body, the weight drops around 30%, down to 100 grams. Pretty usual for an airbrush with that nozzle size.

The difference, as mentioned above, comes from the fact that this is pistol-grip or trigger-type airbrush. They are usually bigger. And here, everything is compact. The hand grip is slightly different. At least for myself, the index finger wasn’t the main finger to control the trigger with. Instead the middle one works better. Index finger with PS-275 helps me with pointing the airbrush tip, while with standard pistol-grip I use that for shooting. And it is still very comfy tool.


Mr.Hobby PS-275 surprised me a lot. At first glance I wasn’t impressed. Then, after a short while, it took all my admiration. The smaller size fits a gap that I didn’t know exists. Pistol grips in general are almost perfect. However, conventional ones does some jobs that are meant to be executed by those only.

PS-275 is in between and still manages to work equally good as those two types mentioned above. The only thing that it cannot be is a single-action airbrush. But I don’t think it needs to. Mr.Hobby did a really great job with that trigger type airbrush. It is cheap and more than competitive. It is reliable and does not have competition with its specific size. My recommendation goes to anybody who is looking to expand airbrush line with similar tool. It can be used very successfully as a stand-alone tool too. It combines the ease of use of a pistol-grip, with the versatility of a conventional airbrush. A very very good choice for any buyer!
