I shoot competitive Bullseye, so my suggestions come from that perspective. I shoot nothing but SWC 185 and 200 grain cast or swaged bullets.
I have loaded & shot over 50,000 45ACP rounds in the last 12 years and tested thousands of rounds in a Ransom Rest.
The amount of crimp is dependent on your chamber dimensions, powder choice, bullet choice, and brass choice.
If you're loading them for casual shooting, crimp to whatever you want. You mention a COL of 1.26" measured per a barrel drop. Make sure your OAL is at least .001 shorter than the hood length. If you get into a lengthy match or practice session the fouling buildup both in the forcing cone and slide face can result in jams in feeding. Don't ask how I know.
If you're loading for competition, 100% feeding is a must. I taper crimp my short line (50' and 25 yards) loads from .465-.470 (100% reliability is a must). If I'm loading swaged lead bullets (very soft) a light crimp is required to avoid deforming the bullet (.470). If I'm loading my cast bullets (harder) I crimp to .467-.468. Never over .468 because I'm looking for the reliability factor and I can't afford to have a round fail to chamber because of fouling at the end of a match.
My long line loads (50 yards) are crimped .468-.470 with all brass except Remington. Remington is thinner and requires .466-.467 to achieve the same level of bullet pull from the case and the same level of accuracy. My first Kart barrel in my wad gun wouldn't shoot unless I crimped them to .463, it was a tight chamber and didn't like anything over .465.
Some powders also will be very dirty if there isn't enough resistance when the round is fired. Experimentation will tell you.
Keep records of what you've shot and the results. Try the same amount of crimp after 300 or so rounds and see if there is any issues. If there isn't you're good to go. If there is, give it a bit more crimp and retest.
FWIW
