Ordered 2 spring kits from Power Custom.

Vaquero - trigger spring, 14lb hammer spring, base pin latch spring.

Blackhawk Bisley - trigger spring, 17 18 and 19 lb hammer springs and base pin latch spring.

Swap out should be easy but I got to thinking... why the 3 different hammer springs for a Blackhawk? I get they're different sized pistols but the action itself (trigger/hammer etc) seem to be almost exactly the same.

Any idea why the difference? Advice on which lb hammer spring I should use?
