I purchased one in .40 S&W the spring of 2002. It is a JS model. Out of the box it was fairly accurate. Actually it shot 4" groupings out of the box at 25 yards. When it was new it rarely jammed. As time progressed it started jamming more and more. About a month ago I went out to the range with it. It was jamming on every other round. I just got sick to my stomach and put back it the bag.
When I got home I took it apart to clean it and as I cleaned it I examined it carefully, you know like on CSI. I discovered a few things:
1>The feed ramp is made out of pot-metal..
2>The slide showed some serious wear as the metal was,
3>much softer than the firing pin was formed out of which....
4>cause accessive wear in the firing pin chamber
I also noted the bulkiness of the slide itself. Anyway, I called the company and within 3 days they sent me a new slide (much sleaker and lighter weight than the original), a new firing pin and spring set, a slide spring, a new roll pin, a magazine keep. The new slides are narrower than original which means that more holters will fit it, and it doesn't look as much like a brick or a boat anchor as it did before.
Before I put it together I polished the feed ramp. That's when I discovered it being made out of cheap, soft metal. It was full of indentations and hard to buff out. I put it all together and have not shot it since. Trade in value of such a gun with all the new parts is only about 50 bucks. Kind of scared to shoot it anymore. Not willing to get rid of it either. I'm afraid of the liability ramifications if you know what I mean. If I do shoot it this week when I go to the range, I post whether or not it jams. I ususally shoot 100 rounds through each pistol I take to the range...so if it's going to jam it will in those 100.
