Just picked up on this thread so I may already be too late and have unwanted knowledge. Firstly some of the older guns now have spares problems, this applies across the board with some guns being more of a problem than others; although at the moment things aren't too bad with the more popular makes; LGR's are fine but there can be problems if the piston head seal 'goes'; I am currently one of several people working on suitable replacement ideas and I seem to have something that is working but early days as yet. In the FWB 600 range the 600 doesn't have a cocking lever safety system but is totally fine if you respect that; the 601 has a safety system as does the 602/603, these models are on-going upgrades of a very good gun you have to really try them to find which one you like. One gun that seems to slip through the net is the Walther 90 SSP which has an ambidextrous stock, cocking system is a bit awkward until you get used to it, but a super gun non the less; also there are some follow - on variants of which I am a bit unsure about but someone on the forum will know I'm sure. Hope this may help more than confuse. Regards abellringer
