Funny this thread was resurrected since I gushed about the 915 earlier in it. I sold it a few months back because I needed something else. I have since replaced it with another 5906. I promptly took off the Hogue's it came with and installed the factory Delrin straight back grips. Such a difference over the curved ones. The 5906 is my new home defense gun (I like the mag disconnect as an added safety feature). I thought of putting Crimson Trace grips on it, but the grip feels so perfect in my hand with the factory straight grips, that I'm leaving it alone.
