I've tried the Big Dot and didn't care for it. I like plain Meprolight night sights. Their tritium seems to last A LOT longer than everyone else's. The Glock 19 sitting next to me has 10 year old Mepros and they're still 100% functional.

I've got a set of Trijecon (?) on a Sig P225 that were installed probably close to 20 years ago and still works. man I like that gun.

I haven't used any Vortex or Lucid products but know they're well thought of.

Not everyone wants a $600 RDS.

Trijicon

I've always found that Trijicon NS dim quicker. I think their "window" is smaller and makes dimming more noticeable.

P225 is a great gun.

I have problems getting even light on each side of the front sight and the elevation (Unless it's all black) gives me fits. I had a Ruger Redhawk back in the 80's I put a gold bead and shallow V on and LOVED IT. Wish I still had that gun.

They could be mepro's, I will have to check.

First Sig I ever owned and it's my most favorite handgun. USED to have a P229 in 40 cal but sold it to a guy at church about 6 years ago.

Oh I might add that My P225 was worked over by John Quintrall back in the 90's. He was noted nationwide as one of the best Sig Smiths around. Found out a few years ago that He and Tedwca worked together at Apple after John stopped gunsmithing.

Siglite Night Sights from that time period are Trijicon made.

Try green rear and orange front NS.

My P229 40s were unreliable.
