IIRC, the 1909s made in Germany by DWM were OK but the ones made under license in Argentina were suspect. Mine is on a DWM action and there are strategic little dimples on the gun and bolt showing it had been checked for hardness, I run a very hot 160 gr. Speer Grand Slam load in that rifle and there have been no problems. If it's a German action there should be a two line inscription on the left side receiver rail.

Our forefathers did not politely protest the British.They did not vote them out of office, nor did they impeach the king,march on the capitol or ask permission for their rights. ----------------They just shot them.
