You can use 2 day shipping even with the whole gun. Ed Brown will send you a mailing label. This way it's them shipping the gun, not you.That would be good news, it's a heck of lot cheaper to send the slide 2 day than the entire gun overnight.
I only have 400-500 rounds through this gun, I doubt it needs a tune-up. But I appreciate the post.Also, I highly recommend the $99 tune up. This includes replacing common springs and just generally checking the gun out. They may even install your sights as part of this package.
