Just for the record, I thought of three off the top of my head. What brought the question on was the Remington Model 51. I just detail stripped one including the grips and was fascinated. The Glock was the second one. No, guns with grips held on with a screw don't count. I'm also thinking of another common one that's currently manufactured. Hmmmm. I'm not sure, also, but I think there are a few more recent ones like the S&W plastics and the Walther 99.
