When I read that Glock was FINALLY going to reduce the grip girth with the 4th gen guns I looked and looked and looked until I finally got my wee little hands on one in person. Finally getting to handle a Glock 19 4th gen with the smallest back-strap I was sadly underwhelmed. It DID feel better than previous generations but it still felt very similar to picking up a chunk of 2x4 timber and holding it up like a gun.
