Standard LEM is like an old DA only revolver.....Barely better than a good knife. IMHO
You need to have the trigger system improved. When the 4.1 LEM came out I was able to group buy the parts and have Bill Springfield install. I spent months at the range not to mention over 2-3000 rounds of ammo before I mastered it. One of my club ranges is 3 minutes from my office, so I would practice 3-5 days a week, not to mention dry firing at home. My biggest takeaway is the older we get and especially people that have worked with their hands, we do not move our fingers independently as well as we did when we are younger. I have noticed a lot people move or grip all their fingers as they pull the trigger, so the long travel of the LEM magnifies the problem. Once you improve your LEM trigger spend a lot of time working your index finger separate of your other fingers. Those finger squeeze exercise tools work, but use the lighter pull/weight ones. Remember you are working on finger flexibility.
The only reason I applied so much effort to this trigger system is for safety. I carry every day, but I am a government contractor, so many times I have to unholster to enter a building and holster when I return to my truck. I carried a block when CHL passed in Texas in 1998, but was always concerned about holstering. One day I had a close call with heavy winds and my jacket zipper, so that’s when I decided to consider a change. I love 1911’s, but anything smaller than Commander size, I do not trust to function. Carrying a Commander in Texas in the summer time is not comfortable, but my P30k is better. Not to mention sweat, dirt, grime, rainstorm and durability. My two cents
I'm probably exaggerating slightly about the DA revolver because I'm very deliberate, much like when I shoot LEM well. I do remember ordering the springs for the Todd Green Special and if I remember where I put those (4 moves since) maybe I'll try putting in those springs. I swear I don't remember shooting the P30L this poorly, but I have a feeling it's definitely the heavy version which I suspect is causing me to pull. I may also play with the grip panels and see if maybe it's slightly too big for my hands - I know it's not USP 45 big though :) :). Heaven's forbid that I'll have to bring my paper targets back out, but if I must....well, I will.
It's just staggering to me how much "easier" and "better" for me the VP9 is. I guess I'm still coming to grips with that.
And yes, practice is good, no doubt about that. Now that the range is 15 minutes down the road, I have no excuse. I've been hitting it weekly. Too much rain here tough and at times you could set up a duck blind and decoys.
Good luck if this a carry firearm. If it is ever used in self defense, this type of modification will be used against you. I don't carry LEM. DA/SA P2000sk and VP9SK. I just bought them and shot them. They are good to go.
Mine is a hybrid - USP Expert Match Trigger Set modified by HK with the Combat Competition LEM, and then I had Bruce Gray do his action job and major reset reduction which was awesome.
