I guess I missed something, because I don't remember any announcement about these being available. It's a Lipsey's exclusive.

Seems like overkill on a 44SP. Plus, oddly, I have come to prefer the stainless GPs.

Still, the couple of 3" examples I fired in AR were delightful.

I GOT ONE FROM LIPSEY'S. VERY SHORT RUN AS THEY ORDERED STANDARD BARRELS WHICH ARE FORTHOMING SHORTLY. I LIKE THE HEAVY BARREL BUT I ALSO LIKE 'EM BOTH.
