That what it looks like.
One way to find out take them off run, and put in some water in the sink for about 5 min, and let them dry, then put them back on.
If the wood has srank, then the water will swell them back.
But let them dry all the way before leaving them on the gun.
Then buy some non wood grips.
Pachmayr has some nice wrap around rubber 1911 grips.
That look and feel good.
JMHO
Good Luck.
