Ok no one talked me out of buying one ( darn ) so I had to go get it. I had read a lot about this cartridge and liked everything I read. Apparently, it is quite a cartridge. Some of the things mentioned in various places were ( in a hodge podge summary of descriptions): (1) because of its shape feeding issues are non existent, (2) it duplicates the 357 mag touted as the best one shot stop cartridge ( yes I know this debate is a contentious one), (3) a police force troubled with big dogs saw one 357 sig round put a big dog down easily, (4) the air marshals use the round because it easily penetrates barriers, (5) five state police forces use it, ( 6) the Glock's flexibility allows it to give less recoil than the revolver with this round, (7) if you believe velocity equals stopping power this is the cartridge for you and (8) the secret service uses it etc etc. Of course I immediately took the pistol to the range to shoot it. I took two different types of ammo with me. Sellier & Bellot FMJ 140 grain ( shoot em up rounds) and Hornady 124 gr XTP (defensive carry ammo). The Sellier ammo gave a pretty good flash and boom. Pretty snappy. Fired 75 rounds through the pistol. Had one brass case of the 75 hit me in the forehead; but that may be because it bounced off the roof of the indoor range which is rather low. More testing in order. Had to hold on to the pistol with this round. This is where the RTF finish on the grip seemed to help control the pistol. I really liked that finish. Don't know how I would like it in a tactical course with 4 or 5 days of shooting though. Anyone have any experience with this? The 124 grain XTP Hornady ammo ( muzzle 1350fps) was very manageable and seemed very tame and was very easily controllable compared to the 140 grain Selliot ammo. No big boom and little felt recoil. I really liked it as a defensive round. Very manageable.

Next I will have to shoot my 40 caliber Glock alongside this new pistol to see which one I would like better. Right now I am leaning toward the .357 Sig. How about you?
