Does the G-21 and G-17 have the same pound firing spring, or is the
G-21 stronger.
I was going to put a Ghost 3.5 connector in both. It says not to use
the 4 lb. spring for SD use, and they sell a extra power spring.
So I was wondering do I need to use the stock spring in the 21 and get
a extra power for the 17 or are they the same. Thanks.

xtra power will give you xtra (10% more spring weight) protection against hard primers.

Since they cost the same as the standard, and I am not bothered by the trigger pull, I use them on all my Glocks with a (-) connector.
