Well I've had good experiences with my Para-Ordnance 14-45 LDA. The only flaw I find with it is the tight barrel bushing. It is accurate and reliable. I've had no failures of any sort so far.
The LDA trigger is a good one. A long, smooth double action trigger. You certainly are not fighting it, making it feel lighter than it is.
If I did not have other suitable firearms, I would look at the 7-45 LDA Companion(?). I believe that is the Commander sized Para-Ordnance.
While I like the LDA trigger, the length of pull throws me off. So it is a fun gun for me. Single action pulls do better for me.
