All the pistols that you mention,will at some point require the seals to be replaced. If they are done with the modern synthetic materials, they will last a life time of the average club shooter. The FWB 100 is harder to cock than the later 103. The 103 is also expensive and hard to find. The Mod 65 and 80 and the later Mod 90 are all still capable (in the right hands) of winning club matches. If your not adverse to CO2, there are a number of 10m match pistols that will do the job your looking for and don't require the cocking effort of the SSP or springer designs
