It would not have come with a three-screw trigger in the model 11, and is not adjustable for sear engagement or over-pull. It does have an adjustment for pull-weight spring tension, not a huge range but it's something. Typical hunter trigger, and quite functional. It's possible to put a lighter gauge trigger spring in it, but it will never be a bench-rest trigger.
The Stevens 200 has the same trigger.
The early heavy barrel/heavy stock version model 12 (maybe 12V) retained the 3-screw trigger until the early 2000's I believe. They were all single-shot receivers
