I am at the same spot you are. I am shooting almost perfect scores (499/500) with the Glock 19 Gen 3 will a Gen 5 make it perfect? I will stick with what I got and see how it plays out. Great topic and thanks for starting it.I've owned a Gen 3, G19 for about 12 yrs now and absolutely love it. Probably the sweetest shooting gun I own. My question is what are the differences (other than grip) between a Gen 3 and 5? I'm thinking about trading in the Gen 3 for the Gen 5 but not sure what the net gain (if any) there will be. I appreciate your comments!
