Low profile red dot scope mount for model 27?

[Mr. Monday]

I have a model 27 that I want to mount either a burris fastfire III or vortex viper rds to. It seems like most people are using the allchin mount but I noticed that jpoint, leupold, and trijicon have their own mounts which all look to be slightly lower than the allchin mount. What do you all suggest using?
