Ive had my RWS 34 Panther for about 3 weeks almost its starting to come along. I decided on a BSA 2z7x32 AO scope with a 1, 1" high piece scope mount (I thought I might go with a 4x16x50 Simmons scope). Anyway my overall impression of the Panther 34 is it it as well made air rifle powerful and becoming fairly accurate. Right now I'm only shooting 15-20 yards at my home range, I've narrowed it down to 3 pellets that it shoots well now, they are RWS Super domes, Gamo Match and Crosman wadcutters. I just got some RWS Meisterkugelns haven't shoot any yet.
As for build quailty it is superior to the Gamo Supreme in material but its not as smooth of course the Gamo is a 2 yr. old gun. As of now they only seem equal in accuracy shooting the same pellet
