In the Gov.

 

Thank you for the report. Failures to feed might be a combination of the magazine and round. As you stated, the Defender fed, perhaps it has a stronger magazine spring.

Of the hollow point rounds you tested, this one expanded quite well after going through clothing, which is all to the good.
