I open this topic for show a new rules for Far West setting, the name is "Sin Piedad" (Mercilessly). It is not a commercial ruleset but its game appeared in the magazine Falcata in last december. The rules are created by a group of friends fans of the gunfight and all everything about the far west.
In my club we played some games, we think about the rules are very well written and we can play great aventures.
Here I post some photos but in my blog I have several entries where I explain tha game rules and the AAR.
I hope you like it and I will can more post here.
Best regards!
