RobTheDog,
You have chosen wisely with the HW30S.
Weihrauch, for some reason, pack the innards of their springers with enough grease to service a fleet of lorries
To put some cherries on the cake, get a rear aperture sight, and /or, send the trigger to Mr. Luke Jolly - he will re-work it to give a safe, crisp 6 oz pull
The below are my HW 'springers' that I use in the MPL - top to bottom - HW30S, HW99S (in the 'camo' stock ), and HW95 SuperMatch)
Have fun & a good Sunday
Best regards
Russ
