If the finish is too rough, rubbing it down should be easy. Wee block of wood with abrasive paper on it, rub, check, etc.
The next Glock design change, adjustable sized grips! They have prototypes all ready... About time, how many contracts have the lost because of not having small hands in view? For me, the Glock 19 is perfect, good for me!
But little people need good guns too!
Personally, I really like the RTF's grip. It's a vast improvement over the old one, imo.
I was looking for the 17 RTF today at show, but no one had any.
