I found a member on another forum in the USA and paid him to mail me a couple for my B22 and A22, purchased from Gunshack. However, while I was waiting I found a bubba-mod where one takes the T-spring and heat it barely orange-hot then allow to cool at room temp. This takes much of the tension out of the spring and got my B22 trigger-pull down to ca 1# or so. With the Walker digital pull-gage I use it's hard to measure much under 1# (low-pull) when the trigger hits the end of over-travel immediately after release. It became waaayyy better than the 2-3# OEM pull. The V-spring did fit the A22 and brought it down also, but the A22 trigger is still stiffer By Design. I sold that rifle as I didn't like the trigger, altho many folks do like it, I'm just fussy about light smooth triggers which the A22 WAS NOT.
Also, Polishing ALL the friction surfaces inside the action will make a big difference, by just being much smoother.
