I've tried everything short of C4 to get the grip off and it will not budge. I'm wondering if the fact that it was ceracoted has something to do with it. I called Kriss and they said to pry slightly on the edge and introduce some light oil to migrate under the grip. That too, was a no go as even thin plastic toothpicks would not separate it to get oil introduced. Any metal like a dental pick would scratch the ceracote. Looks like the Medium grips will be the grip of choice.
You probably don't need to take out the hammer Spring. I was referring more to popping out the retaining pin , that holds the Hammer spring and grip backstrap in place:
Look at one of the extra grips : There's a tab near the bottom : Take a butter knife of a spoon :Or better yet use a razor or knife blade: Put a piece of masking tape on the blade and just slightly wiggle it: put a towel against the gun so you don't scratch it. If you do scratch it a little. Buy a Presto Blue Pen and the scratch will disappear: They cost around $5-$7 The Pen is amazing stuff. Before doing the knife idea. Put it in direct sun for an hour and soften it up.
I would say it's more possible the grip was installed while still warm : So some level of stick and suction has occurred. You did take out the retaining pin I'll assume? I can just squeeze mine with 2 fingers and pop it right off. Try warming it up : I'd be surprised if that didn't work : You should only need the Sun for an hour maybe less.
You have the tool that mine was missing: It sure seems like using that pulling up and out simultaneously would do the trick. After heating it up
