Does anybody have any input on the advantage tactical sights? www.advantagetactical.com. I am looking for a pair of fixed sights for my G22c that are brighter than the stock sights and has quick target acquisition, also allowing me to get a good target picture. I use my G22c for target shooting (mainly indoors) and GSSF competitions. Would there be any issues with the front sight and the ports? Any other recommendations would be helpful, I'm trying to not spend more than $80.
