My Just Right Carbine came with a 10 round mag, no big deal since I already have several standard mags for my 17. The mag has a funny looking follower, with a big hump on it; The first time I used it, it caused a jam when the bullet below the one being fed into chamber, also came out of the mag partially. Is this the standard follower for the 10rd mag? Can I switch it out to another version? I just want to make this mag a range mag, but I want it be reliable. I have not tried it in my G17 yet. Thanks!!
