I injured my back in a motorcycle/car collision in my youth. After a recent lower back muscle injury I decided to make some changes in my carry gear.
I've found that Perry suspenders are great for taking some of the strain off my back and putting it on my shoulders. I use a Milt Sparks VM II, which spreads the pressure of the holster out quite well. It carries a Colt Defender. About as light as you can get in a .45 ACP 1911.
This is carried on a Wilderness E-Z fit, Frequent Flyer belt. I really like the range of adjustment built into this belt. Weighs about nothing. Liking it better than the custom leather gunbelts I've used over the decades.
Need to work more on the software.
These changes have helped quite a bit. No longer have to suffer to CCW.
