I'll do a deal with you. If you send me money for a case of 9mm and 70 mags I'll record a video firing that thing 1000 times.
How's that sound?

Wrong. You have to "start with" metal parts. That whole top portion is metal. What ya got there is a 3d printed grip and some small parts. Lets see some unedited video firing that thing 1,000 times. PLA+ is likely to explode in your face. That looks more like PETG. I would still doubt 1,000 rounds.
