I had the Original 35 rebuilt
Good choice. Spent my life savings on a HW35 at 10yrs old, had it now for 32 years. Did a self fitted rebuild once…. seemed to have a lot more punch after that 😉 Always used the open sight but fitted a 4 x 40 scope a couple of years back which makes it a completely different tool.
Also picked up a mint second hand Airarms S410 recently for £300 so a bit of a bargain. Fast & quiet with a 10 shot mag and super accurate. Not saying you can’t get the accuracy with a springer but much easier to do so with a pcp. Also you could never get 10 shots in as many seconds with a springer which you can with a pcp.
