FWB 65 - one spring model vs. 2 spring
Posted: Mon Sep 02, 2024 7:51 pm
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.
