I did pick up the Glock 22 RTF today. Shot it, hit several bulleyes and performed perfectly as to be expected. Carried it in a Uncle Mikes IWB for four hours. The grip rubbed my love handle raw!!!

If I plan to carry this anymore I will use my Blackhawk Serpa Holsters. Fired the Glock 24 today. It shot perfectly and my 12 year old son was shooting better groups than his old man. Really proud of him.
About the RTF grip, I would rather have the 4th Gen Glock 22 so I could conceal it.
