I've been contemplating picking up the new MK25 to go along with my older German P226's and did a google. I found a thread on another forum regarding rust issues with the spring in the grip. Now, from my understanding Sig did fix this for the guy. The date on the box was March 18th and he bought it April 3rd or so. I'm sure this was either a messing when coating the spring with the phosphate or they used an older spring from a non-Mk25. In any event it is disheartening to hear that a $1,000 firearm can come from the factory like that. Any thoughts or opinions? Thanks. Wanna kill these ads? We can help!
