Hi, thanks-what is a "wheelgun"? While not deadly force issues, I Have had kids come behind me and push canned goods from grocery shelf on my head, (cuts) several laughed at end of isle and shoved grocery carts at me, full speed, knocked stuff off my lap-heavy big stool & needed stitches, pushed me towards street from behind, grabbed chair and spun me in circles. One guy pulled me out of checkout line saying he was tired of standing and I could just sit. Totally no way for self defense but I asked store security if they had video for charges-they didn't want to get involved. Have searched for mirrors to fit on chair to see behind but no luck. I have seen spiked slip on handle covers for w/c but then my son -or anyone- is unable to help when needed. Really worried about "gun grab" and found 1 Etsy person-Larson Tactical- that makes level 2 for Hellcat Pro but $$ savings just went for 7 lb Nemo -Chi Mix-with serious pneumonia.($600) Thanks for all your input. Blessings.
