FWB 65 - one spring model vs. 2 spring
Feinwerkbau 65 pistols were made with a single mainspring, then later had 2 springs - a thinner spring inside the mainspring. The mainsprings from the two configurations have different part numbers. Do any of you here know the different characteristics of the two springs? I have a spring from a single spring gun, but my pistol is the 2 spring model. I'm debating whether or not to assemble it with the spring from the other model. Thanks.

The FWB 65 with a single spring, produces around 475 fps with a 7.0 grain pellet, while the two spring version goes up to 525 fps.
I think oem single springs are compatible within the 65/80/90 series.
