OK the little Jumbo is back together but it does feel a bit low on power. Does anyone know what ft lb they should be? I was thinking about 3, put it up against a Nemesis and the Jumbo has much less power. The spring feels ok when cocking, piston and seal's are all new (thanks to the Record factory) but it just performs a bit low on the power .... or is it me expecting to much from the pistol? Any comments, thoughts would be appreciated. Thanks Russ
