I am impatiently waiting for my 4595 to arrive at the FFL. Wouldn't a 357-SIG H.P. carbine be a gnarly gun? It would be a pistol cartridge, necked for flawless loading. Small projectile with a potent charge behind it. Whew that...... would be the ultimate duty weapon, and mid sniper rifle. My first duty weapon was a Sig p229? I think it was. Man that gun had every LEO and expert shooter at the range gawking lol. It sounded like a 50 BMG. I had to get rid of it tho...... waaaayyyy to much kick, recoveey and back on target criteria. I always thought it would make a badazz rifle cartridge so here I go thinking.. an HP CARBINE.. perfect.
