Okay, I have an Ultra Carry II. I'm not the most experienced shooter, and this is the only gun I have owned. I am having a significant number of misfeeds. I have had some more experienced shooters watch me for technique, and I have had them shoot the thing with similar results. I see a lot of stuff about the 4" models getting better by installing Wolff's 22lb spring (or similar heavier springs to slow down the slide). Has anyone had similar experience with a 3" barrell model? I'd love to know this could be better for $10. Thanks a lot.
