I've never tried a .357 Sig Glock.
But I HAVE tried 10mm, 9mm, .40 and .45 Glocks. I own Glocks in .45 and 9mm.
IMO, the .40 Glocks, especially the G27 and G23 have the worst subjective recoil. I was surprised, because the 10mm is a more powerful round than all the above and SHOULD recoil a lot more. It must be the wider grip size on the G20 that mellows the "subjective feel" of the recoil. The G21 which has the same wide grip in .45 ACP is extremely mild in recoil. 9mm Glocks are snappy, but low in recoil IMO. The two .40 models I mentioned for ME are both snappy and sharp.
If I ever get a Glock in a caliber other than 9mm or .45 ACP it will be in 10 mm. I really liked the G20, it recoils so mildly for a round that approaches .41 magnum ballistics. I'm really not interested in .40 Glocks, I'm sure they work great for most, but they just don't work for me.
