It's possible that because this is a safety feature they intentionally rendered it undefeatable for liability reasons.
I just think it's bad design, and the undefeatability was a side-effect. This was added to the line just a year or so ago. Previous models did not have the device, so the barrel, as it was originally designed and intended, did not have it. It was an after-thought inspired by our lawsuit happy society.
In fact, the first few specimins that had this 'safety feature' (the 'loaded indicator'), you could discharge the round in the chamber by striking the indicator with a hammer
Thank you for your time and advice.
