3.8-4.2 grain at 1.135" OAL will be a safe recipe to start. 4.5-4.6gr is a good snappy load and 4.8gr is about max you want to consider.
BTW, 1.167" OAL is a bit long to load 9mm for a semi-auto. Most magazines limit OAL to about 1.160" range. Under that by a bit is best for function. A good OAL range for 9mm using a 124gr is about 1.120" to 1.145" range.
