Now, take a frame-mounted safety Jericho and, say, a Mossad Tanfoglio, both in 9mm. Those are almost the same pistol. The trigger pull will be the same, the safety the same, even the sights will be the same. The grip will be different, but not a whole lot different. I have a Jericho with the frame-mounted safety and can attest to this.
Move the safety and things change. Go to a single action trigger and things change. Already the sights are different, and the weight difference on the forward frame and the differences begin to outweigh the similarities (which at this point will be the way the slide rides, which is impossible to tell when firing, and the location of the mag release button, which is ubiquitous).
Which is to say, in complete unanimous voices, that these two pistols will feel and operate completely different in all likelihood.
