Glock 34 with comp. recoil problems

[Tackleman]

I have a Glock 34 with a LWD threaded barrel and Maverick comp. Having trouble with slide coming back enough to eject spent round and rack the new round. Tried 11#, 13#, 15# and 17# recoil springs. Have tried several loads, including factory.I have tried 124 gr lead round nose with 6.3 grains of Unique, over all length 1.169. That is a little more than max load. Any help would be appreciated.

Does it run w/ just the new barrel (w/o the comp)? It could be a problem related to the barrel fit or how the chamber is cut and not have anything to do with the comp or loads.
