I leave my magazine loaded all the time. Someone told me shouldn't do that because it weakens the spring. I said BS. What do you say?
Out here in the farm it's not very often I am running in the house to get the gun but it has happened.  Empty mag is no bueno.

Nice!  This is what I carry. I highly suggest a TLR6 light/laser combo. The fit and finish is great. I got mine from Tacticalgear.com for $100.

Also WeThePeople holsters makes a kydex for the combo.

can leaving them loaded weaken the spring by constant compression.....yes, if left in there for "over" a year and the spring was something other than metal.  i have had magazines that had been loaded for roughly 2 years and never gave me a problem.  at least every 6 months (give or take a few) i will take a few magazines at a time and empty them out, inspect them and the ammo, test the spring and reload with the same ammo if no issues were noticed.  now in saying that....... I have several 10 and 20 round magazines that were manufactured in the 60's (shined up for funeral detail) that stay unloaded because they have weaker springs than the ones I was issued in the 90's as well as originally being designed to be a disposable magazine.

I’m not a metallurgist but what I had read is that its not the constant compression that weakens them its the repeated compression and release. A constantly used mag that is compressed and released is more likely to fail than one that is loaded and left for years.

I have a dozen or so AR mags that have been loaded for 4 years sitting in my chest rig near my bug out bag. I may have to run a few to confirm….

I'm not going to mention how long some of my mags have been loaded, it might date me. Dirt seems to be the biggest issue.

Ken, pretty sure you pre date the hammer…..

I’ve had some loaded for years and ran them. No issue with the mag springs, I don’t shoot hammers either and from my perspective their finicky on 1911’s

Yes, they can be finicky. If I have an issue, the mag gets tossed immediately, or beaten with the "hammer" profusely before tossing.
