I have a 20 as well (recently installed a SF lower....don't have small hands but I like it much better), also have a SR 1911 in 10mm and a 5" GP100 in 10mm. You're right, the ten is easy to load for with pretty wicked top end performance. If Glock would make a single stack about the size of a 1911 commander and 10 round+1 capacity I would be a happy camper!I have the Glock 20 and the Glock 40. Plus a Mectech carbine upper which uses the Glock lower and magazines. Easy and cheap to load 10mm and it's a hell of a round when you load it yourself!!!
