Just put a SIG Romeo on my P17. I went with the Romeo because thats what others suggested because of its light weight. Functioned flawlessly. I like the "shake awake" feature. I AM DISAPPOINTED with the size/location of the on/off button. You gotta have Barbie doll sized fingers to get on there.
The sight must have cost more than the gun.......
I've wanted a P17 since they came out, planets never aligned, then last week I found an M&P 22 for a price I couldn't pass up......Happy shooting with that!!!!
