I ordered some of each, and the ISMI are 0.062" in diameter and look nice.

The Brownells are 0.058"

ISMI are 2.5 times are expensive.

ISMI says they are 'heat treated, shot peened, and stress relieved.'

I live in a ban-state, so I can't just buy all of the delicious $10 each magazing deals that everyone else gets. I did get someone to sell me a case of 30 NIW preban USGI mags last year for a good price.

My goal is to make 'high-reliability' magazines that can stay fully loaded for long periods of time.

I am taking apart my old mags, blasting them, Gunkoting them black, and putting in Magpul followers and Ranger plates. I want to make up a set of mags I know I can count on. If any of them fail, I will mark them. If I notice one fails more than others, I will decommission it.

So mostly I am shopping for a spring that will stay compressed and not lose power.

That means I want chrome-silicon, thanks.

I wonder if the military will ever switch to it?

Why not just ask or guess who supplys Brownells springs.

Ah.

I had no idea you made them.

I ordered 6 new Brownells mags and opened the box up last night and found two with feed lips out of spec with very sharp edges, I think they will go back.

There's a discussion about this over at 10-8forums.com; it seems like some believe that the ISMI are overkill and CS is exceedingly sufficient.
