I like the looks of the 43, and I don't even like small pistols....grin.
Maybe the taller suppressor sights for the bigger Glocks will work with the 43 too. I'll bet they will.
I need to check. I know they make different sights for the 42s though. It's probably the same dovetail, maybe a little narrower on the 42 and 43.
Dawson Precision is right down the road. Might see if they are up to the task.
