Airsoft Carbine Kit Conversion Options for Real Glocks

I finally made the jump, and bought an Airsoft EMA Roni Carbine Conversion Kit for my Glock 23. Before I make the review with pics, I would just like to discuss all the airsoft options for the Carbine conversion of Glock pistols as I learned. Take note that all of this was gathered thru informal conversations with the sellers on my way to getting my Airsoft Roni.

I will not be naming the stores or place where I learned these things, first because I am not sure if they will agree to it as I did not ask their permission to reveal these information. Second is I am not sure of the legality of some of these conversions, I think it is sort of a gray area.

I will be discussing options for the Glock, but will spare a paragraph for the 1911 conversion that I saw.

'Main Options for Glocks'
There are about four airsoft options available for converting Glocks into carbines, and these are the Hera-Arms PDW Kit, the Fab Defense KPOS Kit, the EMA Roni Kit, and the Folding Machine Gun Kit.

According to the seller, the Hera Arms Kit was the first kit that was "explored" for use with real guns, and it worked well. The only problem with the Hera Arms Kit, is that it is not as easy to fit your Glock into it, it seems you need to make some permanent changes that will take a bit more time to do. In short, it is not a quick, drop-in conversion like the Roni. I forgot to ask the price for this unit.
