Considered a competent gunsmith now
Follow the directions on Ed browns website and go slow. I Used a file and an Arkansas stone with a good set of dial calibers to check deminsions against the original shoe, everything feels great, not a five review because I haven't shot it yet due to Corona virus quarantine
Excellent trigger, if it needs fitting
I purchased this trigger first for my SAM Elite 1911. It required top and bottom filing to get it fitted in the frame, but once fitted, it works perfect. I bought another one for a RIA Compact 1911A1, and it's too small for slop free fitment. It drops in the RIA and is lighter than stock, but expect about the same play in the trigger as stock. These also don't have forward takeup tabs, so if you don't require that and don't mind some take up in your trigger, you'll be fine.
No such thing as 'standard' w/1911s!
Although the quality and craftsmanship of this trigger is stellar, keep in mind that there is no such thing as "standard" when it comes to 1911 parts. In particular, this trigger does not function correctly in a Para-Ordnance single-stack frame. After hours of fitting/prepping this trigger, I reassembled the pistol only to discover that the pistol didn't function properly. Further inspection with the help of a calipers revealed that the bow is roughly .065" longer than the original part. So unless you're willing to refit all your other parts to this trigger, or you have the ability to swap the bows, look elsewhere if you own a Para. As for everyone else, as I already stated the quality of this part is top-notch, and it looked pretty darn good in the assembled pistol before my bubble burst. This trigger is, IMO, an excellent value, too. My wife, who is the person for whom I was installing this trigger, would have really liked it. My only advice is to measure and compare everything before taking that first file stroke, in the event you need to return the part for a refund.
Great deal on a great trigger
I am not a certified armorer, just mechanioally inclined. I had this baby in and functioning in 50 minutes. Yes, it does require filing, sanding, and polishing, but that's how the 1911 trigger replacement goes. I.B.
