I took my brand new Performance Center Jerry Miculek S&W 929 8 shot 9mm revolver out for testing today. Light for its size and great SA trigger I was excited. First I thought I would try to shoot it without the moon clips. Doesn't work even though it appears to seat on the case rim. The light primer strike on the top cartridge is from my attempt: One of the three moon clips I received would not hold a 9mm case in any of its sections but at least two of them were okay. I went through six shots and recoil was very light due to the barrel length and compensator. I saw that it was shooting about three inches to the left at 10 yards. Looking at the sights, I don't wonder why as they were set to the left. When I opened the cylinder (there were two shots left) a bullet fell out of one of the cases and the case the bullet came out of spilled its powder. This is Federal 9mm in aluminum cases: I made a rough adjustment on the sights and found I couldn't close the cylinder. I checked the ejector rod, the extractor, and under the extractor and no problem was found. Well, I got it from Davidson's so I'm shooting an email off the them. All on all a bummer of a day due to the gun and ammunition. Federal is getting an email also.
