i see people discussing this subject, but not much on how they have overcome it. when i wear a t-shirt tucked and then an over garment i have little trouble, but in the spirit of trying to hide a 24/7 grip during the summer i have been working in a t-shirt only format and have found that i need to really keep after the shirt riding up and bunching on top of the grip. i have been thinking about using a tiny clip on stretchy strap similar to what i sometimes use on my eyeglasses, or maybe making a little ramp or something to lesson the shelf on top of the grip. it also may be i am using the wrong holster. also what are the special t-shirts i have heard about? this will be my first summer w/ the 24/7, i carried a slimmer single stack last year, mostly in a gut belt, but the isw is allot more comfortable.
