I’ve got the M&P, Legion and the X5. The Smith trigger was awful. It now has an Apex trigger which is awesome. I like the X5 and Legion way better than the M&P. They fit my hand better. I have small hands and thought the Smith would be a good fit but it seems too narrow for me.
The Legion is relatively new and doesn’t have many rounds through it but my X5 is north of 12000 and it hasn’t skipped a beat.
