Hello everyone,
I’ve been a longtime reader but am now a first time poster.
This is my third year shooting open and I have managed to go through nearly every possible problem one could have with an open gun.
Last week I noticed that my gun had chewed up its upper barrel lugs pretty badly. I was speaking to a friend and he asked me if my gun passed the shuemann test. I’d never tried it so I have it a go. Sure enough it did not pass the first test where you insert a 0.020 “wide shim into the front of the ejection port when the barrel is 0.25” unlocked. I can’t even stick in a 0.010” shim. I tried the test with a second open 2011 and it’s the same. I also tried with a limited gun by another manufacturer and it’s the same.
so here is my question, in the shuemann test it’s suggested that you need to remove some material from the frame in order to allow the barrel to tilt lower. Problem is that my barrel will not tilt any lower even if it’s removed from the frame with the slide. This is because the tunnel the barrel sits in in the slide doesn’t give it sufficient clearance to tilt more. Is this normal? Does the timing test even apply to a modern 2011 open gun?
I’m really confused at this point and hope that a gunsmith will read my post and help me understand. Both open guns have bull barrels. If I need to increase the clearance for the shims do I remove material from the barrel or from the slide?
