Isn't it about time Glock released a 4" version in 10MM? The grip on the 29 is terrible for all but the smallest of hands and the 20 is not great for concealed carry. The Glock 19/23 size is among the most popular size for an all-purpose handgun and it seems like 10mm now has the traction to warrant more options. Would be nice when traveling to states that actually reciprocate for carry to just have one handgun.
