...If anyone has experiences with other 357 SIG pistols I would love to hear about it....
I have and own the .357sig in the following pistols with the triggers:
Sig P226 (DA/SA)
Sig P229 (DAK)
HK P2000 (Heavy LEM)
HK USP357 (DA/SA)
HK P30L (Light LEM)
Beretta Cougar 8357 (DA/SA)
IMHO, the best pistol is the HK P30L because of the easy trigger, balance, lowest felt recoil and ergo grip. Quickest follow-up shots and accuracy is 1-inch groupings 10-12 yds out.
Second best is the Sig P226. Slightly more felt recoil than the P30, and the short reset trigger helps a lot. Rate of follow-up shots and accuracy same as P30.
All others are a distant third because of the trigger systems. Heavy or gritty DA pull, heavy break, long travel between break and reset, etc. The worst is the Beretta, but that is another story.
