The recoil spring on the 238 is weak and only has 2.75 inches to work with, causing it to only last 600 rounds because it crunches down against itself too easily. The 938 has a stronger spring, it is longer. And the guide rod has a little cup for the spring to back up into. It lasts longer.
I too have over 1300 rounds on mine...without replacing it. Experiencing no failures to feed except a few in the 1st 100 rounds during break-in. It's been perfect since then. I put 100rds a month on it just to stay current with the action of it.
