My experience with scopes on handguns is limited to Leupold 2X & 4X. As was mentioned, with this brand, loosening the lock ring on the eyepiece and moving it back will increase magnification and lower eye relief - good for offhand and bench work. Laying down Creedmore with the pistol further out you will see a large dark donut with the sight picture in the middle. To fix, move the eye piece forward, the picture increases and no donut. Magnification will be lowered. So if you have Leupold 2X, forget Creedmore. Your target will be a tiny little image. Creedmore with Leupold needs at least 4X. But now when you go offhand, 4X is a lot.
The best overall solution is the Ultradot sight. No need to fiddle with the eyepiece, it is constant good eye relief, 1X is good out to any handgun distance, it is tough and backed by good service and warranty. Good service means they don't try to mess with you. Some companies are adversarial and hostile. I think Leupold is more hostile than before. They are corporate and stingy. Ultradot on the other hand seems more committed to winning credibility, at least currently. They are using the old Japanese model of business ethics. If they do good for you, you will come back vs the typical corporate American model of we've got your money now, #$%^& you. Things do change though. But it is good to notice and mention the service publicly to weed out those corporate mentalities who just want to suck the money out of your wallet.
