I have a G27 I really like that gun.
It can be bigger to carry then you think, my brothers G19 feels almost the same as carrying the G27
Highly recommended, get the Desantis Leather Holster, feels good to carry
I only got the G27 because I have 9mm glock already (I wanted a gun that shared calibers with what cops carry), otherwise I woulda got a G26... I recommend it because .40 ammo is a bit more pricey and if this is your first gun
