Innovative Gunfighter Solutions is a company in Milford, Michigan that specializes in customizing firearms. The photo above is of their IGFS G26L. The base gun is a Glock 19 that has had its grip chopped down to the size of a G26’s grip. The grip has thumb index points, mag release scallop and stippling. The trigger guard is undercut with a forward index undercut (this prevents “Glock knuckle”). The slide has top and radius serrations.
I think this pistol looks amazing. I don’t know why Glock does not have their own shop to produce these kind of custom pistols, although it did take Ruger 50 years to figure out that there was money in tactical/semi-custom Ruger 10/22s.
