What 40 Mike Mike said above.I’m going to go against the grain and recommend the G29 over the G20.
Why? The platform is more versatile. It will accept a weapon light or laser. Shorter in overall height than a G19 with flush mag. Accepts grip extensions and factory OEM 15 round G20 magazines for a reload or home defense.
Smaller footprint and somewhat lighter than the G20. Concealed or not, the G29 is simply easier to carry.
Aftermarket extended barrels will get you to G20 ballistics and beyond for the G29, if needed. Personally, I think Buffalo Bore 200 grain hardcast out of a G29 is a great woods combo, even from the 3.78 inch barrel.
For general field use or carry, G29.
For dedicated handgun hunting, G40 with MOS capability.
I have the G29 and my son has the G40. I can put a lone wolf 6 inch barrel on my G29 and it becomes just as accurate and hard hitting as the G40. My son and I have stood side by side and exchanged weapons. If you don't look at the weapons the G29 with the six inch barrel feels just like the G40.
There is nothing you can do to the G40 make it as easy to cary as the stock G29.
It might be ugly but it works.
