I have a question for standard Walther P99 owners? Have any of you had a trigger job on your P99's…..? I understand there are some gunsmiths offering to reduce the DA first pull from ~10# to as little as 7.5# and the SA pull as light as 4.5#. Have any of you had this done to your Walther, was it successful and what/who did the trigger job. Thanks, Helopilot.
