Similarities between Graco SG2 and SG3

Coming from the same line, these two products share quite a few similarities.


When comparing two Graco products, you know it will be a tough fight.

Graco is a company with a great reputation, known for its build quality and innovation. There’s no doubt that Graco makes some of the best sprayers and spray tools out there on the market today.

They also place great emphasis on the ease of use and comfort. There’s no questioning why this brand is a favorite among painters.

Fundamental similarities

Apart from having the same manufacturer, Graco SG2 and SG3 also share a few fundamental similarities. For instance, both devices make use of the Graco Magnum airless system, one of the best on the market today.

They also both come with the same four-finger trigger, the same guard locking mechanism, and share almost an identical design.

Compatibility and comfort

Furthermore, both devices are built with comfort in mind. They are easy to use, easy to clean, are perfect for practically any paint job with any paint type, and can be mastered easily by most DIY painters.


Both SG2 and SG3, as mentioned earlier, make use of the Graco magnum sprayer system and are sold separately from it. The price of both is quite on the higher end but is not considerably different from each other.


Here we’re going to be exploring some features and functionalities where the SG2 Metal Spray Gun is different from the SG3.


Yes, we’ve listed it as a similarity and yes, now we’re listing it as a difference. It was listed as a similarity because both prices are considered pricier than other spray guns, which can be cheaper but can’t be compared to either the SG2 or the SG3 in terms of build quality and functionality.

That said, the SG2 is cheaper than the SG3, and since affordability is relative anyway, it may be a good choice for those who want to spend less.

Gun control while spraying

Both sprayers give you great control while spraying. This could have very well been a similarity rather than a difference, but thanks to the fact that the SG3 has been made a little more comfortable to use than the SG2, we had to chalk it up as an upgrade.

Customer Reviews

When it comes to customer reviews, both the Graco SG2 and SG3 are well-loved and well-reviewed by customers across all marketplaces.

The reason for this is simple; Graco is quite a popular brand and the products do what they’re supposed to do at a very high level of accuracy.

Many buyers praise the ease-of-use of both products, which is kind of the unofficial trademark of Graco. Most of them are not professional painters, so they’re looking for a spray gun that fits their needs, and it looks like both the SG2 and SG3 are a perfect choice.

Some users single out the ease of maintaining both products as their favorite part, which isn’t surprising. Those who are familiar with airless paint sprayers are aware that cleaning and maintenance are the toughest parts, and once you get your hands on a device that is both easy to clean and maintain, it’s hard not to show full-on appreciation.

Finally, an aspect of both products which is also mentioned many times by verified customers is versatility. The fact that you can make use of these guns with pretty much any material, from latex to oil paints, primers, stains, and varnishes without any issues is a big pro.

All things considered, when it comes to customer reviews, both products are highly praised.

Graco SG2 vs SG3 Spray Gun – Final words

Obviously, by now, it’s clear that there isn’t any clear-cut superiority between these two amazing spray guns. In the end, one could say, it all boils down to what you prefer.

The truth is, Graco SG3 Metal Spray Gun is just an updated version of the SG2. When we first tried the SG2, we asked ourselves how can they upgrade this already great spray gun, but Graco managed to surprise us, again.

Considering that the difference in price is not sky-high, we suggest you buy the SG3 Metal Spray Gun. However, if you already own the Graco SG2, there’s no need to buy the SG3.

Either way, thanks to similarities in features, comfort, compatibility, and design, you’re just as safe going for either of them. One thing’s for sure: both devices are customer-favorites.

Another win for Graco.
