A good "universal" sight adjuster/installer will cost $500-1000+. The cheap "universal" installers will work with many different slides, but they don't do any of them well. Been there. Done that. A good one for each pistol brand is the best option, as they work better than any universal or cheap installer. They'll cost $100-200, each. I like MGW, especially for Glocks. The "All Glock" tool costed about $150, but it's worth it. No hassle, works every time, easily, and NO damage or binding. It locks the slide by the rail grooves, accommodates all Glock slide sizes, and about 1/2 dozen sight brands I've tried. The performance is similar for other pistol brands. If you are installing or adjusting night sights, or any other sight that's not just solid steel/plastic, they are a must to prevent damage. If you go cheap, you'll get what you pay for. Find the installer you want, and shop around. Brownells has many/most of them, but their price+s/h isn't always the best. START HERE
