Thanks Flyer. I had a stroke almost 3 years ago. My right side was affected. So I will have to buy one and have someone install or I may try to magnetic one mentioned in another post. I guess this will work on the seven round mag. I started carrying due to my loss of strength and coordination from the stroke. After being attacked by a street person and not being able to defend myself, I got my concealed and carry permit. Out of 20 people in my concealed and carry course I fired and perfect score. I am 6'4" and weight 240 lbs. I used to be able to defend myself and family but not now.
