I recently bought a Whisper X in .177 caliber and I have just fitted a CDT trigger - superb. After more pellets have gone through it I'lll give it the Maccari spring and lube treatment. Possibly this will be one I'll keep for some time. I read the excellent review of the Whisper posted by Gene and CDT posted on this site a couple of years ago and the results obtained from the rifle speak for themselves. So far I'm pleased with my choice but I was a bit disconcerted to read Gene's comment about Whispers having 'poly' barrels with steel liners instead of solid steel barrels like the older Gamos. I'd just like to make sure I haven't misunderstood this point. Do all Whispers have the 'poly' barrels and steel liners or is this an innovation (hardly the right word) which Gamo have recently introduced on the Whisper production line? If the former, I'll just have to be careful with it. I'd be interested in your reply, Gene, if you spot this message among the hundreds of others. Many thanks in advance.
