Does anyone know if the rear adjustable sight is the same on the Beretta as it is on the Colt?

I've looked on JSRs website and the rears look the same, but the fronts look different. They cant check as they dont sell guns anymore so wonderered if anyone on here can answer it?

Also does anyone know if there is a difference between the standard front sight and the replacement adjustable front sight?

Cheers
