I have a Taran +2 and have been really happy with it. Carried it for about a year. Function has been great. That little 43 isn't a high mileage rig for me, but I trust it. I went with the +2 to get the spring. I didn't feel comfortable with the +1 and using the existing spring.
I leave one mag stock in case I need to be very discrete while carrying. It gives me the most chance to be concealed.
