Firstly, I own an original Roni that I purchased from the TSE. I also purchased a chinese knock-off to compare the quality. The copy is nowhere near as good. The clips break easily, and the fit and finish is cheaper. Also, the adjustable stock is iffy at best. The original, on the other hand, is very robust. I sent the copy back, it was so bad.
Is the copy worth $125.00? No. Is the original worth $500.00? No. Are they worth owning at all? No. After you have pimped out the Roni and purchased the Glock, you could have done better buying a decent tactical toy. The truth is your handgun cannot be "both fish and foul". It will always be either one or the other. I still own my Roni, and will play with it occasionally in 3 gun matches, but I wouldn't recommend wasting any money on it.
