At a point in time, not all that long ago, I (a dyed in the wool, long time single action only Bullseye shooter) decided it would be worth my while to learn how to use a double action revolver---double action---perhaps not with the very precise results I was accustomed to; but a damn sight better than I could do at the time---which was basically worthless---much as it pains me to admit it.
The gun I chose to use was not part of my collection, but my father-in law's 4" M&P, bought new in 1920 and carried daily in the hip pocket of his overalls---for 50-60 years, It was not pretty. It also had the very worst D.A. trigger pull you can imagine (22 lbs.)---having had its rebound slide spring replaced somewhere along the line by Bubba---apparently selected based only upon the fact the spring would fit in the hole.
Enter Jerry Miculek's trigger spring kit--one that allows you to dial in your desired trigger pull with ease---with the only proviso you don't go below 7 lbs.---lest your gun won't go bang.
I set it at 7 lbs. It goes bang---even with WW ammo because I didn't have any Federal (that which was recommended for use at 7 lbs).
Okay, so much for that. I started off shooting at large targets at very close range (10 yards +/-)---point and shoot---no aiming allowed. I was properly amazed at the results! I could hit these large targets at close range with no problems at all----shooting rather rapidly.
Then I started paying attention to the results achieved by others-----aiming---and at the distances encountered in a Bullseye match. Achieving that level of skill is going to take awhile longer---if I live long enough---which ain't likely.
