My M&P 45 mags ar a bit stiff getting #10 in but I find the more I do it the better I get to the point that I hardly notice. You just need to shoot more.
I've got some arthritis in my hands and have a tough time loading mags (and opening jars!). Probably have about half the strength in them I did 20 years ago. Uplula works great for me and most likely for other people in the same boat.
You can definitely tell the people that fire a box or two in an outing from those that burn several hundred or even 1000+ apart in this thread.
