Yeah ive just heard a lot of good things about the round, and I would rather have the full stength of the 10mm then the 40 short & weak
I've got a glock 20sf in 10mm and its a great package. I run full power 200gr jhp handloads and its a controlable beast. I like knowing that I have a reliable & compact pistol capable of taking a deer if need be. It's pretty accurate but you have to know that the glock legendary reliability is a myth, mine has had jams of all sorts. It's rare but it happens. Overall is buy it again in a heartbeat, but you better be able to reload.
You must have gotten a lemon because I have 2 G20s and a G29 and all three have been dead-on reliable.
