Glock 20 Gen 3SF or Gen 4?

[DHart]

I'm considering buying a G20 Gen 3 or Gen 4, or a G40. :-/

Any more current (February 2017)  thoughts on reliability differences between these three choices?

DHart, welcome to the forum!  I will say that the G-20SF and G-29 (before SF) are very reliable and great shooters.  My only changes have been to swap to the Wolff non captive recoil rods and 22 lbs spring for the G-20 and the 21 lbs set for the G-29.

While I have some aftermarket barrels I do use the Glock factory barrels for some load development.

Best regards and enjoy the forum.

+1 on the G-20SF (Gen 3) and the same modifications Shadow mentioned.
I've run everything from weakest PPU to hottest Underwoods & Buffalo Bore. 
Confidence is high in G-20SF as it continues to be go to sidearm for woods or hunting.

My G40 hasn't missed a beat...but the more important question to ask between the guns you mention is, what is your intended use of the pistol?

I bought my G40 primarily for hunting deer, black bear, and pigs....secondary use is protection from whatever might be threatening me and the family when we go on pretty long ATV trips up in the hills.

I considered a 20, and it would have worked OK...but the longer barrel of the 40 appealed to the ballistics junkie in me.

My intention with the G20 or G40 is for home defense and defense out on the trail.  I don't intend to do any hunting.  Perhaps with that in mind, the G20 Gen 3 or 4 is likely a most sensible choice for me?

I love my Gen 3 SF G20.

i dont have large hands. medium,. maybe smallish medium.  I am 5.9 175, not that knpwing what will help anyone else. shooting the G20.3SF isnt a problem, but follow up shots are hard to keep on target.  Not blaming the firearm. i dont limp wrist it, but hard to keep a solid grip on it. considering having grip reduction done on it. love 10mil
