You may want to rethink that. It is well documented that Gen 4 Glocks have had a myriad of problems. I have no personal experience, but from what I have been reading, the issues are not yet 100% resolved.

There are several forums and websites that outline some of the stuff with various manufacturers stuff. Might be worth a 'search' prior to investing in one. If you must have a Glock for some reason, a Gen 3 would probably be a better choice at this juncture.
