I have a Glock 34 with a LWD threaded barrel and Maverick comp. Having trouble with slide cycling enough to eject the spent round and load 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. Trying to find loads with Unique powder. Any help would be appreciated.
