I have a Para P12 .45 acp with alloy frame, which is what I carry when I carry. The gun is absolutely reliable with RN, HP and handloads - but doesn't like WC or SWC bullets. I have about 2000 rounds through it. It's a fine carry pistol.
I suspect that the reason you don't see a lot of mention of Para Ordnance is that the value offerings of 'loaded' pistols by Kimber and SA is attracting most shooters.
For those shooters not interested in either the fine DA trigger of the Para LDA or high-capacity mags offered by Para, Para fairs poorly against the 'loaded' offerings by Kimber and SA.
My most recent 1911 purchase is a Springfield Champion Parkerized 'loaded' pistol. This pistol was 100% reliable out of the box, requiring only a trip to my local pistolsmith for a 4# trigger.
It seems obvious to me that the 'loaded' pistols are giving Para and other competitors real marketing problems. They have to be a problem for pistolsmiths also, since the features offered require few after-purchase mods.
