Would a 13-rd mag for a Para Ordnance Warthog work with the older P10 (that I bought in 2000)? Google searches aren't coming up with many options for P10 mags of any sort. I like the way the gun shoots, but I've only got the two original factory mags. Another .45 is not in the cards right now, either.
Seriously they do seem hard to find. CDNN seems to think the P10 and Warthog can use the same mags, and I would think both being wide body 1911 they should be similar. The first and third links below would be where I would start, but you could call Para to see if they can confirm the Warthog compatibility.
