Lloyd - thanks. I was afraid I would hear (read, actually) comments like that. I like my old Commander, it has been with me for a very long time and has been reliable. It's my main carry gun. But, when the plunger tube came loose again and blocked the slide safety from being disengaged all that changed. This is the 2nd plunger tube it has had in 40 years, so I guess that's pretty good, I think.
But, it seems that every other Commander sized 1911 out there has the fully ramped un-bushed bull barrel and that's not what I'm looking for. Maybe I should trade it for a new Colt, even though I don't care for the company's politics or quality control programs, but we will see. Thanks again. Mikey.
