I put a set of the Ameriglo Pro I Dots on my Glock 32 and I love them. They give you very quick target acquisation and look great. The best thing is the quality of them is 2nd to none. They are Ameriglo sights with the Trijicon inserts, the sights will actually be stamped with the Trijicon logo. You can find them at a variety of places, I got mine at grabaguns.com for about $75. Here is a link to the Ameriglo website showing what they look like.
i'm running mepros on one of my 32Cs and with a center hold, they are dead on....i had wanted to try the ameriglo I-dot pros (gl-212-220), so i ordered a set....my only complaint was that at 7yds, i had to use a 6 oclock hold to hit the bullseye....using a center hold at 7yds, my shots were two inches high consistently....i talked to Rick at ameriglo and he said that the only other front sight they could offer in i-dot pros would bring me down one inch....so i opted to keep my mepros and now i have to got through the hassle of selling this set of i-dot pros :(
