I've owned my Daniel Defense M4V11SLW for 4 years now but I've never owned a pistol. I also have a CZ Double Barrel shotgun. I'm now in the market for a Glock 19 for mainly home defense and periodic range fun. I've done a fair amount of research and I'm torn between getting the gen 3 or gen 5. I want my wife to able to shoot the gun and I've read that the gen 3 is not as ideal due to the grips. She's a petite 5'3". I'm planning to buy the gun from GlockStore in San Diego. I want to get the tactical trigger job on the gun to reduce the trigger pull to 3lbs. Since I'm doing this, I'm not sure if it even matters which gen I get. What's your guys input on the matter? Thanks.
