Hey Wendal I haven't seen anything in print, but I noticed huge price increases in the secondary market on mags. Seems all the supply houses are sold out and there will be no more produced.
Have seen asking prices as much as $100.00 for a 10mm and $80.00 for a .45 mag. Thankfully I always buy a nice supply of mags for any semis I purchase. I wouldn't sell my 3G Smiths for anything! So many were made, I wouldn't worry about finding parts. Of all I own I've never had to replace anything except a spring.
