We have designed a new retaining pin for the P-10-C's magazine release, as well as a new mag tension spring.
We feel the retaining has considerable room for improvement.
We have noticed the OEM mag spring has a tendency to "bend" to one side after use. The new CGW mag spring will be music wire and should prove to be a better part.
The new design mag retain pin is probably 5-6 weeks out, the mag springs will be available in the next 2 weeks or less.
