After reading a couple of threads regarding “reloading” or magazine swaps ( No peaking: Reloading without looking and Reloading speed ), I did some snap cap reload drills with my Sig Sauer P938 last night.
Results were a bit disappointing because after inserting and racking the slide on the replacement magazine, the magazine was frequently falling out on the ground. I stopped to investigate and found the magazine release was not consistently engaging and retaining the magazine - even when the magazine was pushed all the way in. It would sometimes require multiple hard insertions and “taps” to get the magazine retained in the grip.
Did the internet search and found many people have had this issue. Some of the “gurus” suggested buying a different spring, cutting it to length; others said stretch the original spring, and finally I started finding posts that said Sig recognized the problem and came out with a 2nd generation magazine release design that I found no issues reported.
I took mine out this morning and did a RemOil blast inside the spring hole. A lot of black residue came out. I reassembled and tested and it seems to be fixed. I guess enough had built up over thousands of rounds of firing to impede the spring’s function.
It being New Year’s Eve, I am going to wait until next week to contact Sig to find out if my SN has Gen1 or Gen2 design installed.
Just wanted to post so others with the same model would be aware. We all know it is better to find out in training rather than active self defense.
