I can't comment on the single-action 18.9, but I have the 18.9 LDA LTD and couldn't be happier with it. I picked it up, along with an LDA 7.45, when they first came out. I use it in the SSP class at IDPA and its accuracy really pays off at the 20 yd. stages. It has the best double-action trigger I've ever felt, in revolver or auto. It makes a nice alternative to my Glock 35 in SSP
