Found a short, excellent, Gray Guns vid on removing the safety from the FCU. Then, found a couple good treatises on the trigger swap. Question is, once that safety is off, is the rest of the process just like in the other vids, where the model shown doesn't have a safety? Thanks.

Yes. It should be the same as changing it out on a non safety model.

Thank you Phil. I think I am one of the odd-balls who will prefer the curved trigger, and I have the comparison pistols to see for sure. Now, I just need a round-to-it, LOL.
