My used SA Micro has been throwing a stovepipe every now and then (3 in around 2-300 rds). Range guy said it was bad ammo, but it's the same ammo I use in all my range sessions and I've never had a stovepipe in any other guns, even an almost identical Kimber Ultra. Shot some Federal HST, and promptly got a stovepipe on the 4th round. So much for ammo as the culprit!
I'm thinking either a mag problem, or the short barrel is causing a mean muzzle flip that launches the next round at a bad angle to the barrel. One problem could be I'm using Kimber mags in an SA gun?
