I never knew these were available yet until a couple popped up for sale on GB. There are a couple of youtube videos out but I wanted to see what sigforum shooters had to report.

I have one. It has a very nice trigger for a small pistol. I have a G43 and a SIG P365, and the 503 has a better trigger.

The only drawback of the 503 is it’s low capacity. Also, it could use factory night sights like the p365.

A 503 with a double stack mag with 10+ rounds would be very cool indeed!

Played with one side by side an APX carry. Thinner than the APX! Trigger was pretty nice. Slide seem tall from the rear. Priced @ 499.00 seemed a bit high. Hope they bring out a “hi cap” version.

Big turn off was it looks like a rebranded P290 ( ugliest gun known to man).

Thanks guys. It is a nice looking pistol.
