I know there is a current system called "Convert-a-Pell," for most revolvers and semi autos. They use a pellet especially designed for this system, reg pellets will blow their head off. The kits range from $40 to $75 I believe. It is the same basic concept as this "Pip Squeak," but has an easier priming system and more accuracy. I have a few of them for my dads different guns. They sell direct from the internet. They are currently avail at the following:
