45C: Fair enough. I own rifles featuring both systems. Some old...some new. Though I have no really hard objection to the add-ons, I also prefer the simplicity of the original rifles. They worked just fine in their original form for well over a century....adding on additional gadgets seems to be trying to solve a problem that didn't exist.
Wherever possible though , I either remove or disable(Where mechanical function or safety won't be compromised) these safeties, etc. Mostly for practical reasons.
For example: Miroku-Winchester 1873. Finely made and functional rifles. I bought one a few years ago, as a back-up rifle for competitive use(Cowboy Action). The new rifles feature a rebounding firing pin extension system, as their safety. Which I fully intended to replace with a solid extension right from the start....as part of planned modifications to the rifle. I'd heard various reports about this system being unreliable, prone to failure, etc. So, not being one to rely on unsubstantiated claims...decided to test it out for myself.
A year later and about 10,000-plus rounds, the rifle was still functioning perfectly. But, I went ahead and swapped out the extension, anyway. For no other reason than to simplify the fire control system and ensure reliability under the hard use seen in competition. Also, to make this rifle feel and function as closely as possible, to my main match rifles (Uberti 1873). Consistency between one and the other being the goal. The Uberti rifles being very nearly identical to original 1873's in design and function. The Miroku-Winchester too, at least externally. Internally, a bit different.
In the end, I am indifferent to the incorporated safety features found on many new lever rifles. As already mentioned, I think they scratch something that doesn't itch. My ultimate interest being one of function, rather than appearance, when it comes to guns. But like you, if I don't like a rifle, I won't have any problem disposing of it.
