The P94 in .40 is a very, very reliable and durable pistol. It never misfired a single time in the thousand plus rounds I shot through it--no failures to feed, no stove pipes, no jams, no nothin'. All kinds of weather, all kinds of ammo--it just keeps plugging away.
It's also not the most handsome of firearms which was why I ultimately traded it in on a Beretta Cougar. I now wish I hadn't--not because the Cougar's given me problems, but because the Ruger was the only .40 in my lineup. Now I've got to replace it (gotta have a gun in every caliber--that's my new goal...) and I think to get a weapon as reliable and as stable of a platform for the caliber, I'll have to spend a lot more money...
The P94 was my first automatic and my most reliable. It set the standard for what to expect from subsequent later purchases--and few have matched it's performance with all types of ammo.
