I've had my P94-4 for about 6 years now. 427 is right it's an aluminum frame with a steel slide. I don't think they ever came in steel but don't take my word for it. What works for one person doesn't always work for another so keep an open mind. Your best bet is to take the time to find a range or gun shop that will rent out pistols so you can try it. Yes you'll have to shell out some cash for it but you won't make the mistake of buying a gun you don't enjoy shooting.
If you're just not wanting the flex of a plastic gun I think you'd be happy with it. The 94 handles the recoil quite well I think. The felt recoil is, to me at least, about half of a glock. Yes it is heavier than a plastic pistol but that's also part of what keeps the recoil down and keeps you from having to fight to keep it on target. I use mine as a duty piece at work so I'm willing to stake my life on the reliability. I really enjoy shooting mine, and I'm lucky enough my job pays for range time. Honestly I haven't ever run into anyone that didn't like they way it shoots, but like I said give it a try first. That's my two cents. Hope it helps.
