I have a single stack 4053. My only .40. I should get rid of it but I can't bear to part with it.
As nice a trigger as my S&W 66 shooting DA. Maybe better.
Eight rounds in the mag, totally reliable and accurate.
The single stack 4053 (and 4054) is built on a frame intended for .45/10mm. Not quite as skinny as the 9mm frame but not bulky since there are no controls protruding from the side.
I hate DA/SA, perferring a consistent pull.
