Trenavd Posted July 16, 2004 Share Posted July 16, 2004 On my open gun, STI frame, slide, Nowlin barrel, major 9, with a hard chrome finish, the slide has developed a problem going all the way forward. When I lower the slide slowly by hand on an empty chamber it stops 7/32 short of going into battery(which appears to be about the distance a slide goes reward to unlock), a slight pressure or bringing it forward with only slightly more speed and it snaps into battery. When running the gun with a recoil master installed I was having the same problem fairly frequently, by switching to a std rod and 11# ISMI spring it runs better but still stoped a couple of time today. Any ideas?? I have checked for burrs and find none. the locking lugs are square and appears that the gun locks up tight, it is a fairly new gun with about 3 to 4,000 rounds through it.

Kingman Posted July 16, 2004 Share Posted July 16, 2004 Check to see if your reverse plug twisted slightly. I have had that keep some guns just a bit out of complete battery. The other thing would be to inspect your barrel and lug very carefully for any cracks or stretches in the lug(wear). Link to comment Share on other sites More sharing options...
Jon Merricks Posted July 16, 2004 Share Posted July 16, 2004 I take it that the only time it does this is when it's loaded. If so I was having the same problem. The rim may not be going all the way under the extractor. I'll try and find the link from Brazo that tells you how to check the clearance on your extractor.

Carl Posted July 16, 2004 Share Posted July 16, 2004 Also make sure that the extractor tension is not too much. I had a similar problem with my 9mm Open gun, with an Aftec extractor. I had to shorten the front spring by compressing it with pliers for a few seconds (Aftec instructions detail this procedure). If you are using a standard extractor, you will have to take out some of the "bend" do this carefully, because it's easy to go too far.

Trenavd Posted July 16, 2004 Author Share Posted July 16, 2004 No this is happening on an empty chamber when I lower it by hand so the extractor should not be the problem. Link to comment Share on other sites More sharing options...
Chriss Grube Posted July 16, 2004 Share Posted July 16, 2004 Does it run ok with ammo? is it it a problem then too? Link to comment Share on other sites More sharing options...
warpspeed Posted July 16, 2004 Share Posted July 16, 2004 Has it done this since day one? Link to comment Share on other sites More sharing options...
Trenavd Posted July 16, 2004 Author Share Posted July 16, 2004 I think I found it. Checked for interference by the recoil plug and found it was hitting the comp just slightly. Thanks for the help. Link to comment Share on other sites More sharing options...
Kingman Posted July 16, 2004 Share Posted July 16, 2004 Not a problem. I have found it becoming a common occurence. One of my friends just bought a para race gun and had the same deal. I also had a little bit of a problem with the racegun I just built for myself. Link to comment Share on other sites More sharing options...
Jon Merricks Posted July 16, 2004 Share Posted July 16, 2004 I had to have a custom plug made for my recoil master. STI cuts there reverse plug channel too deep and there is not enough metal on the end of the reverse plug to take off without having problems down the road.
