JPro45 Posted March 7, 2004 Share Posted March 7, 2004 First, Thanks to all for the great topics and discussion here on the forums. I recently put new ISMI srpings and SV comp followers in two of my 140mm SV mags. Both have Dawson basepads. Today was my first outting with the new components. In 200 rounds I had three FTF. All were the same. The slide stopped on the round which was nose up in the ejection port. Always on the last round in the magazine. All other rounds in the mag fed without incident. I purchased the gun used and it came with the magazines. They were running fine before I cahnged the springs. I know, I should have left it alone, but I thought new springs and followers would be a good thing. The gun was manufactured in 1997. What could be causing this problem? Do I have to send the magazines out to be tuned? The gun is a short dust cover SV. I am running a 12.5 lb ISMI recoil spring with a blue Wilson buff, FL stainless guide rod. The hammer spring is factory. Thanks in advance. Quote Link to comment Share on other sites More sharing options...
