13lb Hammer spring - what can I expect

[surffisher]

Interesting.  I had one light strike on my P-01 out of 50 rounds the other day after putting a CGW 13lb spring in. I had none in about 200 rounds prior to that with the same ammo (Fiocchi 115gr). I’m about to put a CGW extended firing pin in but keep the stock spring, since this is my CCW. I chalked up the one light strike to the ammo, but now I’m wondering.  Glad I already planned to put the extended pin in.

You could still chalk it up to the ammo since Fiocchi tends to have primers on the harder side. That's were the balancing act with lighter springs comes in. If you were shooting federal or handloading with Federal primers which we know are about the softest primer out there then you probably would never have an issue.
