Things I liked:We purchased our .177 Gamo Camo CSI about 1 month ago, and it is a wonderful air rifle. Am so glad I listened to others on youtube, and other WEB sites an ordered the Gas Venturi upgrage, though it sounds expensive for an additional $100.00, it is worth every penny! No recoil,none! We had our good budies at Pyramyd chrono the gun, very high consistent numbers. This gun is used by both my 16 yr old son and myself. And we both hit targets and get very tight grouping at 20 yards. Not bad for an air rifle! The rifle is very light, and the real tree camo is much better looking in real life the the pictures on this WEB site . Everyone that sees this gun, love it, and once you fire it, you are totally hocked.
Very Very Accurate, easy to hold, no recoil and great balance. All round fantastic rifle for its price, can compete very well with rifles costing hundreds more.
Things I would have changed:Gamo means lazy trigger... no exception here either... very long pull. We are going to swap out the trigger next month. But if you decide to keep the factory trigger, it only took my son about about 20 shots to get used to it, and probably a few more for me. But you can master the trigger with a little patience. Its just not competition set up, and probably the only weak point to this rifle. What others should know:The Scope is on back order from Gamo, so Pyramyd shipped us the rifle rather then have us wait for the scope, am so gald they did, its been over on month and the scope is still on back order from Gamo. I find that the rifle shots very tight groups with many different pellets. We use Crossman Premier Ultra Magnum (very good), also Gamo Rocket, Beeman FTS Double Gold, Gamo Match, Gamo Magnum all have very tight groups.
I can not say enough good things about this rifle, and the assistance we got from Pyramyd Staff, they know their products extremely well and told us the pluses and minues of other rifles we were considering. I tried to get the same from a local air gun dealer (COBRA), they just didnt seem to want to help, didnt call us back or just plain n simply didn't offer much assistance (I tried engaging them 3 times). Pyramyd is the way to GO! We are extremely happy with this rifle, loved the support from Pryamyd sales. If you are considering a Gamo Whisper... Do yourself a favor and upgrade the the Air Venturi option, hands down the best decision we made. We love it!
