love mine too, just wish I could bulk fill it.
I was looking into this until I found out how the Drulov works.
I had assumed that the co2 bulb was pierced and sealed at the valve meaning that the shots were fired and fed gas directly from that bulb much like a conventional repeating replica.
This method is fine for plinking but I wasn't happy about it in a quality target pistol.
However I've since found out that the bulb goes in upside down and is pierced by a screw in piece that releases all the gas into the pistols own reservoir.
I'm reliably informed that I'll get 50-70 consistent shots per bulb which is fine for me and does away with the need to bulk fill.
