This tool is well-designed through and through. It's well-balanced, feels good in your hand all day, and is upgradeable to fully automatic?great for production speed. And, it works perfectly as a single-fire tool. The box could use some work.

|P3500||No||1/2 to 3 inches||.27 caliber||5 pounds||13-1/2 inches|
This is a powerhouse tool with a good, basic layout and a good price. It's light and easy to maneuver in tight spots. I also like its sensibly laid-out box. It has a hefty recoil and is loud. I wish the grip was a little more comfortable.

|RT400M||Yes||1/2 to 1-1/4 inches||.27 caliber||5.5 pounds||17-1/2 inches|
I really like the spring action that advances the booster, making this a fast-shooting tool. It has smooth action and comes in both magazine and single shot versions. The fully automatic conversion shoots shorter pins than I often require, so it's limited on my sites, but might be great for others. The recoil is noticeable and the tool is loud. I wish it had a better box.

|493 PowerPro||No||1/2 to 3 inches||.27 caliber||5.35 pounds||14-3/8 inches|
This is a very solid tool with smooth action. It's better for one-off work than production speed. It has a good, sensible box with plenty of room for a day's worth of pins and boosters.

This is the price champion?the best combination of features and cost. The tool is well-balanced and deals with both recoil and noise very well. The box is the best in the group and the tool will soon have a fully automatic upgrade.
