I have a Holland & Holland and a Charles Boswell that are both so thin in the wrist it's scary
I won't take them out on a winter hunt as a fall will surely break something.
I have had several of the Reproduction Parkers both 20's and 28's back in the day when I couldn't afford an original Parker. I have never had any issue with them and they had single triggers for the majority of them. They are a great gun at a good price.
