So what’s the process to tighten the grips? Just don’t want to have them rattling like they came from the factory.They are Allen head screws. Don’t know the size, one of the smaller bits in my Wheeler kit fits it. You do know that the screws thread into a grip bushing that threads into the frame. If you mess the threads up you will have to replace the bushing. If you wish to upgrade the screws to give the SR1911 more bling, look at wicked grips.
