I feel your pain. I've finally got myself a LP400 that not only had a left hand grip but was my size too! I don't have the money to buy new and the prices for s/h PCP match pistols meant that by the time I had factored in the cost of grip I might as well as bought new.

Anyway, I now have a perfectly good FAS 604 pistol for sale with left hand medium grip and original case. I was shooting a 87 average with it up to a couple of months ago. £250.
