New to the forum and gun ownership in general. Brought my first pistol about 2 weeks ago, M&P 10mm 4.6". Cleaned it and put about 150rds through it at the range last week. Decided to give it another quuck clean and lube today as I won't have any more ammo for it for a bit and noticed the end of the slide lock spring on the right hand side was out of the frame and resting on the block. It looks as though it is sat in a groove and supposed to be there but i hadnt noticed it before and can't find any info as to whether or not this is normal or a defect. Some people in a reddit post had differing opinions and I have emailed S&W but was hoping someone here may have some insight.
