Well, I just got rid of my last Glock (26; had previously sold a custom 19) and have the Sigs listed below. The neat thing about the 2SUM is that it is two frames, but one gun! According to the ATFE, the so-called chassis/trigger assembly is THE GUN. I didn't know this and thought I could get another trigger to avoid switching out each time I wanted to use the other frame. Ignorant me! But after a little practice, the change over is simple and easy to accomplish. The first trip to the range I found the reg. size frame of the 250 to be much more accurate than I ever was with the G19 and it had less recoil! The compact frame also seemed to have less recoil than the G 26, but it took some time before I could figure what my grip needed to be to get on target. All in all, I am VERY happy with the Sigs and am glad I got them. Glocks are still great guns, but I guess I just had to try the Sig route to find the ones I really felt better owning.
