Not really much thought, I found a good solution with my HW40 - Sold it! - Talk is cheap!
Now, about this lovely HW75 I've bought... as with the the HW45, as i'm right handed, the RHS safety lever interferes with my trigger finger, and therefore my chi... is it alright to just take the screw out and remove the RHS lever? Is the trigger going to drop out or anything if I do??
