My GF's father started carrying daily after years of not. He's got some old shoulder rig that won't work out for him in the summer months. I took a look online because I couldn't even picture what a 910 looked like but it looks basic enough. Does anybody know if it's close enough to a current gun for a Hybrid IWB match? I figure if it's "close enough" some careful work with a heat gun can take care of the rest.
