I had the .40 but sold it as I didn't like the balance. The heavier slide just wasn't right for me.
And I had a 9mm HP that had been made in India. At some point after WW2, the Canadian company Inglis (which built Hi Powers and BREN guns) sold the tooling to India. The finish was simple mil-spec Parkerizing and the front sight was staked in crooked. But it worked. I just wanted nicer ones, which I now have.
But the round hammer will bite my hand all the time. I guess I hold it too high, or have a deformed right hand
The Mark III spur hammer has never bitten my hand.
Anybody else have this issue with the round hammer?
