jumbofrank,
My open gun is a 2011 in .45acp and has a hybred compensator (several ports along the top). During the day I can see the smoke coming up, photos make it look like a locomotive pulling a load, but even though there is a flash, verified by photos, I don't notice it even in the dark. Give it a try, but our bodies adapt when under pressure and stress - loss of color vision, tunnel vision, natural hearing protection, restricted blood flow, etc.
