It can stretch out over time, but I'm talking like a year or more, I had that issue with my 5 way back in the day. However, I've had one for my 5, one for my 5S, and now for my SE and they have all fit the same...snug. Never had an issue with it being loose other than it stretching out after putting it through the ringer on my 5 for about a year.Hey, curious regarding the field case; is there any play with the device in the case? I am close to pulling the trigger on a field case and I keep seeing random mentions of the 5S / SE not fitting as snug as the iPhone 5 as it's apparently a hair's difference in length..can you speak to this at all?
And anyone that has experience with Magpul, it seems like the reports of it stretching out are rather mixed, too. At least with the field case, specifically. Is this something anyone has dealt with?
