I prefer a SIG 365XL. I always carry a single action pistol with the safety always working in the same direction. This way if I am carrying my MIcro 9, (for states behind the iron curtain), it operates the same. the SIG gives me a twelve round mag and with one in the pipe I have thirteen rounds.
I love my Kägwerks slide release, it’s an accessory with a purpose and it *werks* well. It does have a tendency to scratch the slide but it doesn’t bother me. It goes on a tool that’s meant to be used and I don’t baby my guns when I use them.
