The spreader is a must have. Wish they had the DVD on a thumb drive and a format I could use, but there are plenty of vids on youtube to figure out how to do things. I had the lips on my mags tuned in minutes, including polishing the lips. Good stuff.
One more thing... A bit daunting to take a hammer to your mags but it works.
Better than expected

I have a set of 9mm that have 5 seasons on them. All were starting to have issues. About a half hour and they are all up and running again.
Great tool to have

After watching the video, not hard to do. Make sure u have a very solid vice.
Near to perfection

The thickness of the tube at the feed lip area was also an issue for me on one mag. 2 others brand new were a mess and now work as they should of. In the future I will only purchase MBX mags. Out of six mags purchased new 3 didn't lock back, one of the Mags also had a bad spring after all the measurements were completed. With out this I would of sold my sti. Special thanks to Dave for this product.

Takes the mystery out if setting up your STI mags. I bought 2 new ones and both were out of spec. This kit and the video make it fairly simple to set them up and helps you learn why and what you are trying to accomplish. Plus, now I have the tools forever.
Mag tune review
Posted by Jennifer Gasparas on Dec 19th 2016
Works well. Mags now fall freely from gun as nearly all dimensions were not within what was recommended. My only complaint are the pliers for the mag lips. Being a ldy ahooter I have rather small hands the oers spread so far apart it was difficult to get a good grip on them to apply enough pressure to spread the mag geed lips apart to reach the correct dimensions.

Dave does great tutorial that makes tuning mags very understandable, and the tools provided are high quality, and performs tuning jobs easily, and precisely.
Good to have

The anvil and pliers are VERY handy.
There is one dimension missing and I feel it is very important.
The thickness of the tube at the feed lip area I found to be crucial. It certainly keeps the follower in the proper orientation.
STI MAG TUNING KIT

Wow! After watching the dvd I decided to give it a try. I did 5 mags total. The first one took about 20 minutes but after that I did the other 4 in 1 hr. This makes it so nice to know after mag changes several times and dropping them on hard surfaces that I can tune them back to like new in minutes. Thanks for the help! Gary Williams
Great way to have tuned Mags!

I just recently purchased an STI Edge from Dawson. Obviously, one magazine is not enough. I decided to purchase the components and do the tuning myself. I already had everything that was needed that wasn't part of the kit. The DVD instructions explained the process well. The tools included in the kit were exactly what was needed.
I took the three newly tuned magazines out for a cruise around the course the next day and they performed flawlessly. Frankly, I wouldn't pay someone to do it when it is so easy to do yourself. Simply follow the instructions and measure carefully. I also installed Dawson base pads and followers at the same time.
