I live in the Tri-valley area and trying to find someone who has had a grip reduction on G17 GEN 4 preferably. My wife has a G17 Gen 4 that she needs to adress her grip to shoot. Thought of a trigger adjustment (see other thread). I have contacted Lane at Cold Bore and he suggested I look locally because of the type of reduction to get an idea. Appreciate his honesty. So if anyone knows a local gunsmith in the East Bay/Central Valley, can you provide the info. Thanks everyone.
