Never tried either the Crosman or the Gamo, but thought the HW40 was a lovely pistol that has led to me getting seriously hooked on 10m air pistol. I sold it after a year to put towards a more serious target pistol but really enjoyed shooting the HW40. Cocking was relatively easy, light trigger and very accurate. Think the Gamo is much the same as the HW40 but without the fibre optic inserts in the sights is more akin to a proper target pistol. Sure there'll others with some real world experience of the Gamo or Crosman who can offer opinion on them.
