Funny you should say that about the trigger, coz i said the same to some lads in the US yesterday, the grip is very snug and is very light and probably good for fast snap shots, but the trigger feels, well kind of stiff and girly.
I think removing the trigger and polishing the ends of the pivots with some brass polish would solve the sluggish movement.
My lad has got the same barrel on his Cocker. Good grouping, and not to heavy.
With the Ion bellow on the stand they do look very similar, but players say it's a total different story to use, but theres a lot of difference between the PMR and the PM6/PM7's
