The gun was purchased new in mid-'08, had run about 400 rds. through it since. Started shooting it more recently. I've already called S&W and they're sending me the stuff to ship it back to them. Just curious if anyone else has had a problem like this.
This is the note I'm sending back with the gun:
I had a significant problem with failure to feed (chamber a round) during my previous range session. I was unprepared at that time to troubleshoot the problem.
After that session (as I always do) I cleaned the firearm prior to taking it back to the range.
The next range session I took (3) mags (mags are numbered, all S&W) with me and loaded 15 rds. into each mag. I proceeded to fire all rds through mag #1 followed by mag #2, with apx. 15 - 45 seconds between each shot. No problems with either mag/rds. I then inserted mag #3 and after the first shot the next round failed to chamber, I had to cycle the Charging handle to get it to load. Every round from then on had to be manually “charged”. Sometimes the round just wouldn’t chamber and sometimes it would jam (partially chamber).
I thought I found my problem (w/ mag #3) but I proceeded to load mags #1 & 2 again and they both were performing the exact same way as mag #3 even though they performed flawlessly previously.
The problem seems to manifest itself when the weapon gets hot, I remember the previous range session the weapon was working fine at the start too.
I have used predominately Fiocchi .223 ammo since I purchased the weapon. Apx. 80% of all ammo through it has been Fiocchi and I’ve never experienced a problem before now. I used 2 different boxes purchased from different locations during these last 2 range sessions.
Any ideas (other than send it back to S&W)?
