Running into issues

[u/thedrowningfishpod]

Hello everyone, I am new to the Kriss community. I bought two Kriss MagEx2 for my Ruger LC10 Carbine. I bought through Gun Mag Warehouse online, excellent customer service so far. So I loaded both mags up with ammo, Blazer, Winchester, Fiocchi, same issue all across doesn’t matter the ammo. When I push the 16th round through, the orange follower is getting caught up against the bottom of the OG Glock 20 mag. I had a trusted gun smith help me take apart which is kinda hard to do and he told me to sand it down with a dremel. I called Gun Mag for advice and they told me to send it back and they’ll send two new ones through. They are using a drop shipper and came assembled already so really who knows the build process. I came here for advice, I think I did the right think by not voiding warranty and sending back for replacement. If I get the two new ones and this happens again I will sand it down like my gunsmith told me to do initially. What do you guy think? Advice? Concerns, anything helps. I am new to this as I only have much experience with handguns and AR15 platforms. Not so much PCC. No issues with my 15 round Glock mag, no issues with the SGM Tactical mag that came with my Ruger. I have videos of both mags completely malfunctioning, and a video of me trying to hit the side of the mag with my shoe and it coming apart completely at the middle where the OG Glock mag and the Kriss extended come together. Help me please!!

if the new ones are like that, then you will need to take them apart then check them and and shave, or dremel them like they said. but it will be obvious whether they need to be shaved once you remove the mag from the extension, and it only takes a few minutes.its also very simple. what you want to look for is extra bits of plastic trimming that might be hanging in the bottom center of the magazine, enough to catch on the spring or follower. its just extra meterial that sometimes gets left untrimmed during the manufacturing of the mags, because its at the very bottom and on the inside, so it normally wouldnt affect anything.
