Myx 365+3 magazine extension - XTech Tactical MTX 365 9mm 3 Round Magazine Extension for 12 Round P365

The item is nice because it extends the 12 round magazine to 15 rounds. Even though it’s not the 17 round magazine that you can buy it gives you a full grip. Two things I have had an issue with the extension after shooting twice with them is some springs do not push the round guide up to stop the slide. The second thing is that all of the parts were not in the ziplock bag they come in.
