I agree totally. I have the three green dot TRUGLO TFOs on my Springfield 4.5' XDm in 45ACP and really, really like them and then with my S&W M&P 40c, I ordered that one with TRUGLO TFOs, but with green TFO in the front and two yellow TFO dots in the back. I wasn't able to find any set up like that locally, so I went against what's typically the best advice, by my 'buying before spying', even though I knew from working in the field of vision and optics, that green's the spectrum the eye sees best. Dumb move.
Most places charge about $5 0r $10 more for the green & yellow combo, but I paid $76 and had a S&W certified armor who worked for the company, put them on for free, as I bought the gun and sights there new for $439--total, w/ free shipping & no tax or credit card 'uptick' and it was $515 total--not too shabby and I think that's there everyday price unless suppliers go up on them.
A small part of it is that obviously on the much bigger 45, the sights are higher profile and 'stand out, actually 'up' a bit more, but in the end, the size of the DOTS is what's most important in these two cases, the sizes are the same--and I can readily see how green is better--more readibly visible--instead of mentally 'matching the colors and aligning' with green & yellow, I am basacially just aligning three green dots that match.
Next time, whether it's a laser or sights, I'm going (staying) green.
No, the green with yellows isn't bad--it's still better than my Tritium Trijicon, Sig Sites, or Mepros for sure--the dots just are a bit bigger and brighter--they're 'just right'--not overdone a bit. My eyes aren't so great anymore, but my 14 and 20 y/o sons agree also.
There are some other sights I understand that are very similar to TRUGLO TFO's, but from what I gather, they're more for guns that aren't at all common, where TRUGLOs either don't fit or might not have the 'look' some guys will pay anything for--it's not that they're any better-the ones I saw just looked 'snazzier' and were going on a tricked out STI frame, custom 'one off' 45 pistol and a couple very tricked out tactical rifles.
I guess for the next 15 minutes anyway, (about as long as anything stays 'state of the art' anymore--lol) the T.G. TFO's are as good as they're able to make.
