As I have never sold one of my Glock's, it matters not.
I met Gaston Glock, in 1984 in The Royal York Hotel in Toronto. One of the subjects of our conversation, was the smooth finish on the Glock 17 (we had bought the first 10 17s, direct from Austria to come into North America) our little gun company was called Practical Pistols Inc. Long gone.
Back to the too smooth finish, according to me! Gaston stated that the Police and Military testers liked it!
Then the Gen 4 finish came out? Exactly as I requested it, in 1984! By far the best none slip finish to date. IMHO. Carry mine every day.
A word to the wise, with the rise of ISIS Thank you Obama. And the lone wolf attacks all over the world, carry every day, and what we used to call Hi Cap capacity, at least 15 round magazines in your carry pistol.
The driving a vehicle into a crowd, and shooting, or stabbing by the Lone Wolf driver, the new norm, expect that coming to a Town near you, any time soon!
Stay aware, and armed.
Something we can do, the German and French Citizens can not do!
Merry Christmas all.
