Sig MPX owners...Step inside

I'm wondering if anyone has experienced the same issue I've had. When trying to chamber a round from a fully loaded 30 rd magazine I'm finding that the bolt doesn't go completely forward like it should. If I try using the bolt release it will get hung up just about every time. If I do the slingshot method using the charging handle it will work correctly but only if I really let it rip.

Anyone else experiencing this? I really don't think I would trust this gun if I had to do a defensive reload. Other than this issue it feeds all types of ammo without fail

I shot mine for the first time today without any issues. I only put about 200 rounds through the rifle, so I will keep an eye out for the issue in the future.

My mags were REALLY tight when new. Took several range trips before they would seat and the bolt would close 100% on a full mag. Now that I've got around 2k rounds through it all seem to have cleared up. Of my 10 mags it was worse with 4-5 of them than the others, I chalked this up to the others having been loaded/unloaded a few more times while I waited for the rest to come in.

Mine's a Gen1, but I've not had the first problem with it.

Mine's a Gen2 Carbine.

I'm still having the same issue on occasion. I have a question for those of you that own one. When you chamber your first round are you A)using the charging handle while the bolt is all the way forward or B ) using the bolt release while it is locked to the rear? 

Also, I had 2 FTE's while using Freedom Munitions so it doesn't seem to like that ammo for whatever reason.

I always use the charging handle on all rifles out of habit.  I rarely, if ever use the bolt release.
