I thought I should follow up this thread with what I ended up doing. The first thing I did was put a new trigger in the Springfield. I got a C&S Tactical Set 2 that included a new hammer, sear, disconnector, hammer spring, and sear spring. The pieces are supposedly tightly machined so you don't need to do any fitting to your gun, and they harden (and test the hardness) the moving parts. It was a bit of work, but I went slow and it all went as it should. The Springfield's trigger is _much_ better than it was before, and I am pretty happy with it. They want you to run 100 rounds through it before you fully trust the trigger (10x 2 rounds in the magazine, 10x 3 rounds, 10x 5 rounds) and it passed with flying colors. I am really happy with this change, and for the first time ever I'm pretty happy with the Springfield. And as a bonus I understand the internals of a 1911 much better now.
Of course, now that the Springfield is sorted out, I couldn't stop there.
I decided on a Pointman PM-45, but unfortunately the times we are living in caught up to me. Dan Wesson is in NY, and they've been shut down for a long time. Neither my LGS or his distributors had one in stock (or the 9 mm version either) so I was out of luck. I just checked and the DW web page says that they are still shut down. (I am biting my tongue so I won't comment on NY or its Governor that considers firearms "non-essential".) I wasn't going to give up that easily, so I started scouting some of the other LGS's to see if there were any left on a shelf anywhere. I didn't find any, but I did find a Nighthawk Talon (used) for sale. Once I pulled the trigger on the Talon I was sold.
It is a joy to shoot, and the way that all of the pieces fit together even makes it fun to clean. I took it to the range and shot the best I have for a long time, and I expect to get better as I learn it better. I may still get a DW down the road, but right now I'm pretty happy with the Springfield and Talon. Hmm, maybe a DW ECO for carry...
