Is that grip tape on the front strap?
Muzzle flip on the little suckers can be a bit much when you're doing quick follow ups. If the tape starts to peel or chew your hand up, you might want to try some Hogue Combats.

Since it's your first 1911, you may want to do some reading on the ergonomics of the beasts. Google Massad Ayoob, a few article from him can be found online. He goes into great detail about what he found to be the proper hold for a 1911. It has worked out very well for me. I'm able to hit silhouette within 25 feet without aiming, just pointing. At greater distances, his hold provides a rock solid platform to shoot from.
Your poor Glock is going to be lonely sitting in the safe while your new piece will see a lot of range time. They're an absolute dream to shoot, even with the shortened barrel.
