Study looks at how well magazine springs hold up over time in storage and with use

Have you ever wondered how well your magazines are going to hold up? I know I’ve wondered that not to mention there are tons of armchair warriors on the Internet offering up their opinion or parroting others. So, what are the facts?

On the AmmoToGo blog called “The Lodge” is a very interesting report entitled “Magazine Spring Torture Test” that reports the results of an actual study they funded. The analysis was done by Applied Technical Services and is very much worth your time to read it.

The magazines tested is quite a list:

  • Magpul Gen 2 Pmag (30 round)
  • Magpul Gen 3 Pmag (30 round)
  • Magpul Gen 3 Pmag (40 round)
  • Amend2 AR-15 Magazine (30 round)
  • Lancer AR-15 Magazine (30 round)
  • USGI AR-15 Magazine (30 round)
  • Smith & Wesson Shield 9mm Magazine (8 round)
  • ETS Glock 17 Magazine (17 round)

Hope this helps you out – I found it very interesting. Finally results from a real study that you can review. Kudos for them to take the time and money to produce and share this!
