So to summarize, the company selling mag springs thinks they wear out constantly and need to be replaced. That’s funny.

My experience is that I’ve bought plenty of extra mag springs over the years. The intent was to replace them at first sign of trouble. They are all still sitting in their plastic wrappers. Mag springs tale a loooooong time to wear out.

The only caveat I have experienced is aftermarket mags sometimes come with really weak springs. KCI Glock mags are great. Once you round off all the extra flashing and put in new springs.

Sure. And the oil change shops recommend oil changes every 3000 miles.

Yeah, and all car makers maintenance recommendations are rediculous and only to insure that dealer high profit parts and service departments stay very busy.

Still I think their is good info in their FAQ in that not all magazines are designed the same and that high capacity magazines in particular may be pushing the limits of reliable longevity.

Good news is magazine springs are cheap and usually easy to change and as always it is best to test magazines on occasion, especially for that every day carry.

You're right. I bought 5 of their 30 round Glock mags when I couldn't get OEM Glocks and they had a lot of feeding problems.

So I took out their mag springs, took out the extra plastic flashing and put in Wolff springs.

Now they run like a top.

This!

IIRC, a number of years ago a cache of original WW II ball ammo 1oaded mags was discovered somewhere. They all functioned just fine. The real test, however, would have been some WW I mags.

I've been shooting for over 50 years. I've never had to replace a mag spring. Do have some inexpensive Metalforms from the Nineties. Began having problems last year. They were all used extensively back then and routinely bounced off the concrete floor (with bumpers of course). Cleaning didn't help. Given their age and use, I just chucked them.

Having stated the above, I would recommend occasional disassembly and cleaning of frequently used mags. Especially with lead reloads, as they can eventually get gummed up inside the body and followers.

I've mentioned in the past, I had a true expert, a giant/legend in the world of 1911's and gunsmithing in general say to me "springs don't wear out". (and basically that those who say they do are in the business of selling springs) We were discussing recoil springs at the time.

I dunno.
