A month ago, when Midway had the 41 mags in stock (for a day or so) I ordered four of them. When they arrived, not one of them fit. I called S&W and was told to squeeze them in a vise. What??? So I called Midway and arranged to return them (out of stock at the time of the call).
Then, I thought that it is ridiculous to have to squeeze them, and called S&W back, asking for a supervisor. I really wanted to tell them that their 41 mag QC was shot to all get out.
It it true that there are no after market mags, but Smith does not make them themselves either. So, I told the super that they may want to contact their supplier and get this fit problem straightened out. He then told me that they have been hand fitting mags to the 41 for over 30 years. IDK...
So I figured, why not give it a try. I did, and all four work perfectly now. It took some playing around, and many "squeezes" to get them right though. I also had to reverse the thumb button/tab (follower pull down button) on two of them. I found that the larger diameter on the wrong side also causes a bit of a hang up in the mag well.
After posting last week about CDNN having mags, I ordered two more. Both of them also needed squeezing and reversing of the buttons. They both now work properly too. I think that "DIY" repairs to new products should not have to be done, but apparently, it does to some of these mags.
All of the new mags mentioned are marked 5 & 10
