Called optics. Guy cancelled my order and also said the Safariland SLS does not work for the 3.8
So he looked through all his stock and found 2 options.
1: Galco fletch concealment thumb break paddle holster #fl440 $78.46
2: Galco paddle lite holster #pdl440b $29.56
The holster I bought from cabelas looks pretty much the same as the fletch.
But its tan and I'd prefer black so I'll take it back and decide between these two.
Thumb breaks are all I get I guess.
I wish safariland would hurry up and make one for the 3.8.
But the guy said they are a few years behind the gun manufacturers.
Next time I buy a gun I guess I check out holsters first..
Who knew?! Grrrr
Thanks for everyone's help.
