Blaxsun why did you post that pic? Is that a latest version? Never seen that one before?
EDIT: I just checked the CAA sight. They do have a G2 that looks like your pic but they are also selling the G1 for the same price as the G2 right now.
Here are the improvements on the G2..
new design improves integration between the pistol and the RONI.
The pair now function as one seamless unit.
larger gas ports - improves ventilation, allowing gases to escape quickly and reduce heat buildup.
Features a larger ejection port to eliminate jams and stove piping.
Longer upper Picatinny rail -25cm
Design to fit the Glock 18 - the auto switch is exposed to operate.
The cocking handle is longer & tighter on the pistol’s slide.
Optional locking screws – locks the pistol even tighter & prevents quick access/installation if needed.
I dug up some of my "real" Roni G1 pics that I bought from Questar. I spent over $400 on this one...
Here is the one I bought for $120 taxes in. BTW I showed this to a guy that does plastic injection and he said this one is more than strong enough. It is not taking even close to enough impact/heat from the Glock to be concerned about safety...
