Definitely not ready for prime time.
Too bad Sig doesn't beef up the P230 design a bit and make it 9mm. That would be everything the new R51 was
intended to be.
That is a nice gun as I've had a chance to handle one although not shoot one.
I'm not mechanical engineer nor do I play one on TV but from what I understand that type of design does not lend itself to high power or high performance rounds.
Due to its being a simple blow back action. They would need to address that.
That appears to be the major problem with R51 it's a simple blow back trying to handle a high powered round. One of those earlier videos explained that.
It's not a simple blow-back. It's the Pederson action. There is a mechanical delay in the unlock, but it's done differently than the Browning design. The only delay with a blow-back is from the case expanding against the chamber. Big difference.
For the Sig 230 to run well with 9mm, it would have to look more like a Hi-Point.
