I'm considering purchasing a Glock 21 and was wondering how the
standard 13 rd mags are limited to 10 rds. Is the same spring used?
If stored fully loaded, would the life of the spring in a 10 rd mag
be equal to a 13 rd mag loaded with only 10 rds?
thx

I'm not sure if the springs are the same, but I would assume that they are different.

Spring life is determined by the number of compressions and expansions, not just compressions. A fully loaded mag can be stored for years and it will still work as designed.

Start by voting out all the Democrats...then let the Rep's that got voted in that the
ONLY reason they are there is to repeal every lousy gun law in California.

10rd Glock mags are not the same internally as a full cap. More like a blocked off single stack.

Don't do that. Some dems are better than some repubs. Check up on their stances or use the NRA list.

Thanks for your help.
I called Glock and comfirmed it is a single stack mag with a different
spring.
