I have a Sig P322 pistol that was failing to fire due to light hammer strikes. After giving it some thought, I cut off the end of an appropriate size drill bit and made a small spacer to increase the hammer spring pressure. After several days, I finally got a chance to take it to the range and run several different types of 22LR ammo thru it. Out of about 100 rds, I had one failure to fire and I believe that was due to a bad round. The trigger pull was not affected and is still nice and crisp. I probably could have gotten a similar result by slightly stretching the spring but that would have been a permanent change, requiring a new spring if it didn't work.
