It is obvious by the sideplate screws, that both of these guns have been played with by someone. Wether that someone was competent or not can ony be a quess. Even if you pop the sideplate, and also check wether the strain screw has been backed off, you won't know the quality of the work. Having experienced a number of guns that were home gun smithed (by so called artists and tool and diemakeers) they are all crap shoots. Some showed great work others needed a professional to fix.
On gun 1, I would try and contact magnaport to see exactly the work done as they are reputable for their work.
On gun 2, I would take it to a smith and have him look it over inside. Sights are easily replaced or swapped as suggested in prior posts.
Have you checked the timing and double action pulls etc, both reasons to have a smith look at them before buying.
Bottom line. They are both shooters and have zero collector value. Buy the one you like the most have it checked out then fix it up and regrip it to your satisfaction. Then go out and shoot the heck outta it.
My choice would be gun #2. I had magnaported gun and non ported in same model at same time sold the ported one..
