I am thinking about buying a G35 Gen 4. Would like to hear from people who have either the gen 3 of 4. (It doesn't matter much to me, I want the Gen 4 but will buy the Gen 3 if that is all I can find.) I am mainly interested in what you like or don't like about it. I am starting to think that the 35 may be a good addition to my .40 Glock collection. Thanks in advance for your input. Frank.
