Thanks for the info guys. I just ordered two of the 12 lb springs. The Pony is virtually the same size a the R9. I would like to use the Pony in a training class and just want to keep it going for a while longer.
Anyone have any experience with 4mags-n-things.com? The only source for larger capacity mags for the Pony that I have found. Standard is 6, and they also have 10 round mags. They are "Blue", so I guess that means they are not stainless which is what I would prefer.
Thanks again for the help.
