I am a huge fan of flat wire springs, so don't want to go to round wire recoil springs in my SP-01. I understand this means I am forced to use the stock plastic guide rod. I'm having a hard time locating a variety of flat wire recoil spring weights to use in my SP-01, so my questions are:
a) is there a source of SP-01 flat wire recoil springs of various weights?
b) will something else work, i.e. a Glock recoil spring?
c) if a & b are dead ends, is anyone cutting a few coils off a stock SP-01 flat wire recoil spring in order to lighten the weight a little?
Appreciate any help.
