Tallball and I share an affinity for the ACP revolver. Here are some of mine.
Included in the photo (bottom row, right) is the M28-2 I converted to 45ACP in the early 80s. It is also pictured with a 625-6 Mountain Gun which is nearly a stainless steel copy.
I have several variations of frame mounted pins and hammer mounted pins. All can be tuned for a smooth pull.
As for saving a few dollars, anything you save will be well spent on ammo. Chose what you like. Obviously, I like 4” tapered barrels, Magna stocks and grip adapters. Some prefer target stocks, checked or plain. Some of my revolvers have a skinny grooves trigger, others a wider smooth one. My preference is smooth but they all work.
