I bought a Pachmayr grip for my G19 Gen 4 for the opposite reason. I wanted to tone down the grooves for my fat fingers. The shape of the grip feels great, except now there is a sticky texture. It's kind of like one of those crazy wall-walkers you could get as kid from the 25c machine.
@derrickgoins, how does the texture of the Hogue grip feel by comparison?
I had a hogue on my G22 for awhile. I liked it, but after some real hard use it began to rotate on the grip when I would draw. I ended up taking it off and throwing it away.
One option you have is to upgrade to a gen3 frame. You can buy one off gunbroker or gunsamerica for about $200 (usually less). Swap out the internal parts from your grip to the new one and VOLA you have finger groves and a rail for a light. This is what I would honestly suggest. It won't have the same serial number, but you could probably sell the Gen2 frame either in the classifieds here or on one of the above mentioned sites.
If the money isn't there for that, maybe you could stipple the front of the grip to make finger groves?
derrickgoins... Does yours have finger grooves or eliminate them ?
Mine actually has the finger grooves.
And thats what Im wanting. Wanting to add them to a firearm that doesnt have them! You got a link to where you got yours from ?
