I personally don't like either the idea nor the execution. Must understand though, Ideas give me headaches and I have never been comfortable around executioners. Makes me some nervous.
This contraption is simply a solution in desperate search of a problem. The only driving force I can think of, beyond the lawyers, was/is to make the gun "look" more like a traditional Colt. I don't see that as a necessity from a personal standpoint. I'm happy with "Fine from the Freeway" and am not a fan of fixing something that isn't broken or not in need of improvement.
Seems, I am also in full agreement with The Professor of Marvelous fame. The objections seem to be driven by "OMG ..... YOU'VE CHANGED SOMETHING." and of course "It's no longer MY Colt Clone" without consideration, never was a clone .... was a Replicant. Heck, a 3rd generation Colt isn't a good clone. It's also a pretty poor Replicant. Oh, and the new gizmo is an increase in complexity. That alone (complexity) will really start conversation.
If you really want to checkout the hand wringing and wailing into the Night, just wait until the "Retro Fit" parts are no longer available. Uberti has a habit of not supporting previous manufacture when an "Enhancement" is made. Soon, if you break one of the "older" pattern guns, you will have to buy a complete "kit" inclusive of the "new" hammer, pushrod, trigger, firing pin and other assorted hardware for your repair. Most similar to what must be procured for their Toggle Link rifles. Be fun to watch.
