My 1st pcp was a Brocock Concept. It's short and light enough that I can hold it in my left hand and cycle the bolt with my right. I also had a Concept but it was too heavy to do this in the field, so it became a bench gun. The Contour is still my go to squirrel gun, however, since acquiring a left handed Daystate Regal, I'm going lefty with my next rifle, a .177 Weihrauch HW100 BP-K. The Uragans have a side lever the user can move from side to side, as does the Daystate Wolverine. The Daystate Regal is available left handed for an up charge. The BSA R10's bolt is reversible along with the Marauder's. There are some nice left handed guns, but they generally are the more expensive guns, with the Marauder being the exception.
