So converting from leather to synthetic needs sleeving down the TP to keep good shooting manners.
yup.. unless of course you do Mick's version of the synthetic conversion, resulting in a lighter piston and a longer stroke, in which case the larger TP may just be OK - but I'd bet it would still benefit from doing down to at least 3.5mm, if not the full 3.0
Always looking for any cheap, interesting, knackered "project" guns. Thanks, JB.
