You're certainly not the first person with that issue. Crossbreed has recently addressed that issue with their "combat cut" option, where they do pretty much exactly what you did so there's nothing in the way when you go for a solid draw.
Honestly I'm not impressed with the Combat Cut. I've tried it on others and it didn't work for me. Scissors and not caring about my holster being pretty did work for me though.
Not sure if that helps or not
Thanks for all the info, that's pretty much what I was looking for.
