Buying Guide to Selecting the Best Nail Gun for Hardie Trim

Choosing a perfect Hardie trim nail gun isn’t as simple when many options are available in the market. Even if you pick anything without considering your need, then it won’t reduce your work; instead, increase. That is why here, we will discuss some crucial things that you have to consider before buying a Hardie trim nail gun.

Depth Adjustment Option

The fast and utmost thing that you have to consider is nail depth adjustability. You have to perform many works with this gun, and every job doesn’t require equal nail depth.

Some works require very nail depth adjustment, and some projects require an external nail depth adjustment. So if you don’t maintain the depth adjustment while nailing, you don’t get the highest benefits from the work. So depth perception is a must.


Who doesn’t want his/her money worth the value of what he/she buys? So to make your investment worthy, you have to check the gun’s material. A high-quality material can make the gun durable to long last and serve you some extra years without any hassle.

Always choose a gun that is made from aluminum or stainless steel. Never choose a plastic construed gun because the plastic guns will easily break and reduce your work efficiency.


Portability is another must-have feature for a Hardie trim nail gun. As a professional carpenter or a DIY enthusiast, you have to go here and there with your nailing gun to perform the job.

So a lightweight design and portable gun help you to increase your efficiency without sacrificing quality. In this case, which guns are made from aluminum or stainless steel, or magnesium, those are lightweight, durable, and portable. That means 3 benefits from 1 gun.


A user-friendly, easy-to-use, and simple design makes your work faster. So while buying a gun for your Hardie trimming, don’t forget to check out the gun’s convenient design.

Before taking your final decision to buy a gun, experience the firing trigger, magazine capacity, nail size, nail type, adjustable switch, and any other things. All of these are part of the gun’s design. If you can quickly get access to them, then pick them up from the market.

Bump Mode

There are two features of setting in a nail gun. One is single firing, and another is sequential firing. When you need a single fire, then it’s convenient to use a single fire option.

But when you need quick and sequential firing, then a bump mode is very much required to save your time and energy. Even a bump mode increases your working efficiency 2 times than manual sequential firing.

Safety Lock

No matter what things you buy, you always have to check the safety feature to prevent any unintentional accidental issue. If your nail gun has a safety lock that will not shoot without pressing the trigger and protect you, your working material, and your workplace from getting injured.
