I bought the C More "Railway" sight first. I wanted to have a sight that I could move from rifle to shotgun to pistol, (if I need to!). Then I bought a pistol with a C More Serindipity (sp?) sight as a part of pistol/sight package.
I really like the C More, however I have had some trouble getting the pistol that it was mounted on to shoot reliably. The seller warned me that this compensated pistol loves really warm Fiocchi 9mm ammo. So far I have not found any Fioochi, so I have been experimenting with some of my and others handloads.
115 gr FMJ did not work when loaded to about 1125 fps. 124 gr lead round nose worked a little bit better. I believe that these were loaded to about 1100 fps or so.
I swapped out the recoil spring with a lighter one. Now the pistol shoot 99 % more reliably, but I am a little worried that the slid may be battering the frame a little. Plus the slide is a little slow to return to battery now.
I have not made my C More mount for my Tactical Sport yet. I am going to try to get a local aluminum extrusion place near hear to see if they have an extrusion that is close to what I need. Then I will just modify that shape.
I have learned one thing for sure. You should not crowd that ejection port with your scope mount legs. Most of my failures to eject have been brass getting caught between the C More sight mount and the breech face.
I'll keep everyone posted as soon as I have an extrusion that I can work with!
Yours,
Bob Troxell.
