Hello Para matey
I know what you mean, and its areal pain prone.
I use a TX200HC, which has all sorts of safetey devices on it (wont do bugger all unless you cock it properly).
I do hold the lever still. The worst accident I had was bending the barrel on a cheapo by letting it go when I was a sprog...I was lucky.
I know its a nause mate, but its a good habbit to get into if you can (god knows i'm trying )
I reckon they make very efficient finger smashers otherwise
