Better than my 357
Size: 9"
I recently purchased this caulking gun, and I’m thrilled with its performance and quality. The product is exactly as described—a heavy-duty tool built to handle tough jobs with ease. The sturdy construction feels robust in hand, giving me confidence that it can withstand frequent use without wearing down. Its design is ergonomic, making it comfortable to hold and operate, even during extended projects. The functionality of this caulking gun is impressive. It delivers a smooth and consistent flow of caulk, which makes application precise and mess-free. Whether I’m working on small home repairs or larger projects, this tool performs reliably every time. The mechanism is easy to load and operate, which saves time and effort, especially for someone like me who values efficiency. Shipping was remarkably fast, and the item arrived in perfect condition, well-packaged to prevent any damage during transit. The seller’s attention to detail in ensuring a positive customer experience really stood out. They’ve earned my trust with their professionalism and prompt service, making this purchase hassle-free from start to finish. If I ever need another caulking gun, I wouldn’t hesitate to buy from this seller again. Their combination of high-quality products and excellent customer service makes them a standout choice. I highly recommend this caulking gun to anyone looking for a durable, reliable tool for their projects.

Love it! Fits extra long caulk tubes.
Size: 9"
We buy and live in renovation projects (currently on number 3) and so we do a lot of caulk. I had a caulk gun that was similarly priced (a little cheaper), and I thought it was fine. However, it was a little too small to fit the brand of silicone caulk that we use (had to wrestle the canisters in and out), and I finally had enough and bought this caulk gun. I'm so mad I put up with the old one for so long! This one works like a dream. The trigger action is great - it definitely feels like the hun is "helping" me and making it easier to squeeze the caulk out. (I recently had to squeeze a lot of silicone caulk in cold weather and my arms did get tired - but for most of what I do this works perfect!) It also doesn't leak much when you take your finger off the trigger, even without turning the little hook thing in back to release the pressure on the caulk. It doesn't have a cutter - you have to BYO snips. It does have a poker to break the caulk seals. My favorite part (aside from the smooth trigger action) is that it has tons of room for bigger caulk cartridges. No more wrestling tubes in and out of the gun!

Better than the Newborn 250
Size: 9"
This is a very well built caulking gun. I would put it up side but side with the newborn 250. The main differences is that this gun can handle the thickest materials. The only negatives that i see are that it doesn't have a spout cutter, it's a tad heavy and the seal poker could be a half inch longer. Besides that, it's a friggin solid caulking gun. And it's a smoking deal for under $15. The attention to detail is perfect. They use removable pins with c clips instead of rivets. I would be happy with this being my only caulk gun.

This is a must have. Works very easily with heavy calking. Like polyurethane.

High quality caulk gun. Great design.
Size: 9"
Do yourself a favor and buy this! I've had so many of the crappy stamped orange or blue caulk guns that ooze caulk everywhere. This is a great gun and helps with really stiff, cold adhesives. It's built like a tank... I don't see having to replace this any time soon.

A huge improvement from the cheap hardware store ones.
Size: 9"
I have used the cheapest caulking gun that the hardware store sells my whole life. I got this for a project where I needed a more aggressive thrust ratio. The build quality is so nice, and my hands do not hate me after using it for any given amount of time. It is worth it. It feels like it will last me a lifetime.
