I have a Glock 21 and my wife has a hard time cycling the slide. I added a couple different charging helpers and still it's pretty hard with her arthritic hands to do. I was wondering if I could lighten the guiderod weight to maybe 13lbs or even 11 lbs, but I know she wouldn't be able to load any hot loads with that, or so I've heard. I do keep this one for home defense only, so I have Hornady Critical Defense hollow points in it. Are those going to be too much to let the gun cycle?
