Brill, thanks for the tips
Yes regards the slide I do try and dampen it when opening to avoid any wear.
Treating it similar to those break barrel pistols that have the release catch I always try and avoid the clank when returning the lever back by holding the catch open.
I know what you mean though it does feel good to have the opening 'clack' but as you say it's best to dampen it really.
Thanks
Nick
