i do like my custom II, but it still leaves a lot to be desired... i hardly use the standard mag and purchased 4 10 rd chip McCormick mags when i first got my gun... can't tell you how many FTF and slide locks i've had all on the last round of those magazines... i've done everything from adjust my grip to make sure i'm not hitting the slide stop to using my bro in laws chip mags to making sure i'm not limp wristing ... it's still hit or miss on that last round.. i've gone through over 1000 rounds, and actually my last time at the range i didn't have any issues... and yes i do clean and lube that sucker, clean well and keep her wet... it is tight as a virgin and i'm hoping the break in was more at like 1000 rounds than at 500 like the manufacturer says... still like the 1911, just wish i had the confidence it would work as well as it should...
oh, sorry for hijacking.... glad you love your custom II, OP... i do really like 1911s (and i'm a big glock guy, too)... just wish i had your luck!!
