To prevent further hijack, I'm answering this post here in a new one. 1. I think guide rods are unnecessary. 1911s function beautifully without. Personally, waste of money. 2. Again, personally, waste of money. Due to the availability of quality steel parts, titanium FP is unnecessary. Consider the firing system, springs and the effects on each other of a Ti FP is introduced. 3. ...ambi safety... Since I shoot one-handed, I never used the one on my Beretta. It was something that was there. My Colt has standard thumb safety. 4. ...a comp for CC... (sigh) Overall, if you want parts to brag on and it's a fashion statement, by all means, add the parts. I don't see any of the parts above as needed on a carry 1911 with the exception of an ambi safety for you fortunate 'two handers' I've got no input on the tactical vs non tactical version of an ambi safety.
