I love the Dominator. The form factor is just right for me and the three stage design makes it wonderfully versatile. One of the blaster's unique selling points is the 40 dart mags which were immediately appealing to me because I don't like carrying a lot of mags. As awesome as they are, there are a couple of issues with the mags which put a few people off. The more widely known issue is feeding worn darts which has a simple fix, but there is another issue with the mags that becomes apparent when you use them a few times.Even loaded with fresh darts, the dominator mags become a bit iffy after a while with the follower getting jammed pretty often. The short term solution to this is to keep them clean and well lubed with frequent maintenance. Great for the first couple of games at an event but they soon get gunked up again, especially if it's muddy. After a bit of experimentation I have found a more permanent fix.All you need is a small file, some sandpaper or even a small knife to do this, plus a small screwdriver to get inside. Since you need to open the mag up, it's a good opportunity to give it a clean so a cloth or some kitchen roll and some silicone grease would be good to have on hand.Dominator mags are super robust and fortunately very easy to get in to. Using a small flat head screwdriver you simply need to depress the 4 tabs to remove the bottom of the mag. Prepare yourself for it to come flying off followed by the spring.This little doodad is the follower. After a bit of a clean, this is the thing that we will be working on.This is one of the 4 guides that locate in a groove inside the mag and hold the follower in position as it moves up and down. These guides are almost exactly the same shape and size as the groove they run in and that is our issue with the mag design. Any tiny bit of grit or gunk that gets in that groove is going to interfere with this tab which causes the follower to jam. We need to shorten this tab ever-so-slightly and round off the edges so there is a bit more tolerance inside the groove.I have literally taken the very edge off the tab, chamfering it slightly. It takes no more than a couple of passes with the file. Make sure you clean the area again afterwards and try not to leave any burrs on the tab otherwise you will continue to have issues.After that's done you can give the follower a good clean and run a cloth up the inside of the mag to clean any gunk out of the grooves. Making sure it's all clean and dry, a little squirt of silicone oil is going to make everything smooth as butter. I really like the silicone oil you can get from Lidl when they have a cycling event in store. Wilko do some good stuff too but if you're on a budget, 'bumper shine' products from the pound shops are a great alternative.Several events later and I haven't had to dismantle the mags since doing this. Maintenance now consists of depressing the follower, swabbing the inside of the mag and a quick squirt of oil. Much better than the full strip down after every event. If you were on the fence about the Dominator because of reliability issues, this 5 minute job will hopefully change your mind.
