The older models were all metal. And go for a good bit now. And the trigger is simple and easy to work on. The polymer stuff in the "new" model is junk.I bought one way back when I was just getting into guns. It ran like a top but the reviews on them weren't great and the polymer feed ramp kind of turned me off. I didn't keep it very long, kind of wish I had.
I've seen just one for sale in the 15 or so years since and was tempted. If I had other 45 ACP firearms I'd consider getting another. A cool gun for sure.
Heck yeah, 45ACP just begs to be suppressed.
