I had one in 9mm. It was a good gun, but the decocker was messed up. Wouldn't decock ever time i tried too. The lever would go down but the hammer would stay cocked back. Other times i had times when i had the lever down and it still didn't drop, i had to put force on the lever to make it drop the hammer. Sold it soon after i realized that. But shooting wise it was pretty accurate and it had a really soft recoil from being so big and heavy. Loved that about it.
I've got one in .40. I'm not a fan and will probably trade it for something else eventually. I find the grip is too big and mine apparently has some problems with the extractor. It throws brass in random directions, sometimes straight to the side, sometimes straight back at my face, other times straight up in the air so the brass hits me on top of my head. That and the occasional stovepipe make it less than fun to shoot.
I had one, about ten years ago. Had it for a couple of years and traded it for a SIG 239. Loved the gun while I owned it, never had any issues and it shot fairly accurate.
I ='ve heard good things about the P90. I have a P89 and love it although I don't mind it being on the heavy side because if you run out of ammo you can use it as a club
I have a P95 in 9mm. I know its not what you asked about, but I love the P95. It shoots great, and feels great in my hand. I dont think the grip on mine is too big, and havent had any problems with it ejecting at all. I think rugers are generally overall good guns. At least thats what I've heard. I love mine and dont plan on ever getting rid of it. It carries well too.
Like others, I don't have the P94 but do carry a P97. I love it. People say its ugly, but thats how I feel about the Glock. It shoots well and is very rugged. And boy howdy, it is heavy. I paid ~$400 some years back and wouldn't trade it for anything.
