If I understand you correctly, if someone was to install a stronger recoil spring they could install weaker mainspring? The reason I am asking, is that I am very confident in having hummer down on the loaded chamber in 1911. I do understand the special care that must be taken when one is to practice condition 2. However with BHP same condition is less comfortable, because it is much harder to cock hummer when needed. Condition 1 with BHP is also questionable to me because of the absence of grip safety.
