Back before Pardini offered a 32acp in their HP model, I shot with a US Army team shooter that had a Hammerli 280 .32 S&W that was converted to .32acp. Because I never heard of such a thing, I didn't pay too much attention to how the conversion was done. I shot with this guy many times and always remembered him filing the metal portions of a Hammerli 208s so his hand would fit better. After watching him aggressively file away on the Hammerli 208s, I didn't really want to know the details of the 32 S&W to apc conversion. But it turns out, he was on the right track.
