Hi all, great site you have here. I found this forum after I started having issues with my shield 40. I really wanted to know if what I was dealing with was common/normal. I don't normally post to forums but in light of all the recent activity on here concerning this firearm I thought I should share my experience.
About a month ago I took it to the range for the first time in awhile. I fired about 5 magazines through it of three different types of ammo, WWB 165gr, PPU, and Hornady Critical Defense. All purchased shortly before the range trip from a big box store. All of them went off without a hitch, all of the rounds fed and fired perfectly. When I got home I cleaned out my range bag and inspected the brass from the days shooting(something I always do). I was shocked to see that many of the casing were severely deformed in the web area. The critical defense rounds were deformed almost to the braking point. Needless to say I was a little put off by this. I have never had a firearm do this in any caliber, I have heard of it happening though.
I contacted S&W and they requested I send it back to them. It is currently with them and I am awaiting a resolution. Is this normal for these guns? Am I overreacting? I realize the Hornady rounds are a little on the hot side but they are still within SAAMI specs. The PPU and WWB rounds deformed as well although not to the extent of the Hornadys.
I have included some photos of the barrel and Hornady rounds for reference. Any comments, suggestions or questions are welcome.
Thanks, Alex
