I would like to hear what other people think of SIG's new three part design (slide, frame, firing control being the three major components). I would like to keep the discussion centered on the design itself and not on opinions of the SIG P250 per se. If you own a SIG P250 feel free to discuss how you feel the design operates. if you do not own one please just discuss the merits of the design itself. Gun owners as a whole do not always seem to receptive of new things. We tend to be a tiny bit opinionated when it comes to what makes a proper and good firearm. I must admit that I was a bit guilty of this when I first got my SIG P250c. The design is a bit different and the feel is a bit different. I was put off almost immediately and decided I did not like it before I even shot it or gave it any chance at all. Then I started exploring the gun a bit more and really thinking about the new formula. I found myself really liking the three part design. I love how grips are now replaceable as well as slides and barrels. Crack a grip frame or scratch it badly? Just buy a new one. This truly is a modular gun. If you have one firing control mechanism you can buy all three different size configurations to go with it. I also love the fact that the slide rides entirely on metal rails. I have always been wary of guns where the slide rides along polymer rails. I also am not all that crazy about metal implanted into polymer at certain contact point. I always worry about wear between the two different materials where they meet. I know it is probably not going to be an issue but I still think about it. Then I shot it and I found I really loved it. The system seems to work flawlessly. Add to it the excellent DAO trigger SIG produces and I was won over completely. In the end I am really impressed with the new three part modular design. I think it is a stroke of pure genius. I haven't really found a truly negative thing about it or how it works. It does create a slightly different feel when shooting but it is not a bad difference. It is just different. I really hope it catches on in the future. What does everyone else think?
