Hi, I've been lurking here for a while doing research on my next purchase. This sight has been very informative and I think I've narrowed it down to the Thunder Pro 9 HC or UC. I have one question. Is it easier to remove the firing pin on the newer models with the Sig type sights than on the earlier models. This has been a normal part of my cleaning regimen on my other pistols and has always been very easy on my other Pistols. I saw the Sticky on removing the rear sight to remove the firing pin block and so on, but the newer ones seem to have a much smaller sight, so I figured it's probably a different process all together. Looking forward to your responses.
