Welcome to the forum. Short reset is just that, it resets into single action. Single action pull weight is significantly lighter than DA. Most stock Sig DA/SA triggers will have a similar feel and pull weight but there are many exceptions. I carry a 229 elite in 357 Sig and the SA pull is right at 3.75 lbs. DA is 7.0. Only mod is a SIg Armorer super strut and 18 lb main spring. The CZ and Sig P22x series triggers are very different feel in my opinion. The Walther I’m not familiar with. Hope this helps.
