Glock 20 .40 S+W/10mm

[rebel]

Hi folks,

Should I change recoil springs when switching between .40 S+W and
10mm Lone Wolf barrels? I have the Lone Wolf .40 conversion barrel
and wonder if I should be using weaker spring for the short and weak
cartridge.

Thanks,
Bill

I didnt & it seemed to work fine. Check the empties, They should land 6-8 feet away with a proper rated spring.

I use a 20 lbs spring for my hot 10mm and a 17 lbs for target 10mm and .40. My 10mm brass has been loaded as many as 8 times and apparently still going strong. I don't bother reloading .40 so I can't speak for brass life.
