my Sig 229 is a tack driver. my 938 sig is muck more snappier.
Both are metal, not Tupperware guns. Perhaps that's your issue.

I owned a G39-it was chmabered for .45GAPOne should compare the G27 with the G39. The G27 is 6.29" long and weighs 19.75 oz. The G39 is 6.30" long and weighs 19.33 oz. The height for both is 4.17". Barrel length for both is 3.46". So there is very little difference in size and weight. Recoil should be the same, mathematically. I don't know if the 40 S&W being a higher pressure round will have a higher slide velocity thereby being "snappier" than the 45 ACP. You might have to handload to get ammo with the same bullet weight and type at the same velocity. The ammo would have to be tested using a chrono as commercial ammo used different guns and or test barrels so you don't know how they arrived at their velocity figures. It would be an interesting experiment comparing apples to apples, but I'm not sure if it is worth the effort as most people will use commercial ammo anyway. So you may just have to live with the fact that the 40 S&W G27 may be a little "snappier" than a 45 ACP G39. Then again actual shooting of both models with similar ammo may show there is very little difference. Who out there has both guns?
Simple.... recoil is a by product of bullet speed and weight. The 9mm has as much velocity as the .40 but not as much weight, the .45 has more weight but less velocity. The .40 has both good velocity and weight giving it more punch and so more recoil.Shot some .40 yesterday. Which reminded me why I never quite could get used to it. It has a lot of kick/pop/snap to it. My .45ACP felt like nothing after that (let alone the 9mm).
Free recoil calculators show 45 to have more recoil impulse/velocity/energy than 40. In fact 40 should be roughly in the middle between 9 and 45. So why don't I experience that when I actually shoot it? I still say there is something in the nature of the .45 that tames it, like the lower pressure it operates with. Something there just makes it feel softer to the shooter than it should if you go by the numbers.
I'm giving up on 40 again for at least now. It's expensive enough just feeding my 9's and 45, especially with testing all these JHPs.
