not sure if it will fit the rail but not sure of how it will feel, An LP10 adjustable trigger would be a good alternative,
A very good pistol trigger is the Centra Putter, nice wide blade and a very good feel to it, I had one on my LP2 and it worked a treat, another shooter at my club tried it and promptly bought the same for his, there non adjustable with regards to angle etc but excellent quality and ideally you want the pull to be straight back along the barrel line, angled triggers can cause poi errors as tend to encourage side loading on the blade.
