This only applies to P229 9mm mags. The .40 and .357 mags have not changed so yours should work.
The newer 9mm P229 mags are labeled 229-1 and have a capacity of 15rds instead of 13. The mags are also wider at the bottom and taper, or bottleneck in about 2/3s of the way up (same profile as .40/.357 P229 mag) because they are designed to fit the new 9mm P229s that are based on the .40/.357 P229 frame with its wider magazine well. The P224 evidently also has the wider mag well.
