Scandium framed....38 Spl +P load with 158 grainers or heaven forbid, .357 will have HEROIC RECOIL....just sayin'...save your wrists for old age, get a gun that's heavier & yep, the same H&K speedloader marked for the model 36 Smith will work just fine with your 340 if you the courage to reload it after the first five!! Rod
I shot Model 37 with different loads, it's not that bad. It's a little heavier, but not that much.
I just stay with +P, not going to .357.
I don't know why people talk so much about recoil, it never bother me. If you talk recoil, I shot a Freedom Arm .22Mag with 1" barrel. Now you are talking about recoil. The gun is max out 4oz, fit into the palm of a small hand. I shot single handed and it didn't bother me. So it's LOUD!!!
I practice with a Ruger MKII bull barrel, I went competition with a 45 Gold Cup. I practice once before competition and it's good enough. Recoil never bother me at all.
I don't want to get into debate, I shoot with hands relax, not squeeze the handle. The more I squeeze the handle tight, the more my hand shake and more I feel the recoil because I fight it. I relax and just let the gun bounce up. I don't feel the recovery time is longer at all. It's the same and it's a lot more comfortable. That's just me.
OK, I never shot a .44Mag, .357Mag didn't bother me at all even with a 2 1/2" barrel revolver.
Ha ha, you know recoil of what gun shock me?..... 12 gauge shot gun!!! That was recoil!!!, My shoulder was black and blue afterwards. I thought those AR15 must be strong too, NOT. It's only a little more than those .22LR. I was bracing for recoil and then "pud"!!!! that's it!!!!
