It went together great. Just enough file fitting to make it interesting. Polished all the trigger components and ended up with a 41/4- 41/2 lb trigger. Finished with some ceramacoat, made a custom holster and called it done. It's very accurate and totally reliable so far. Enjoyed the entire experience.

Received kit last week. Good quality. Price point was why I bought it. All other 1911 kits are WAY over priced and never complete, need to buy slide, extra, buy frame extra, By the time you are done you have a nearly $2000 kit. If you have never built a 1911, like me, you would like to start cheap. I own three other Tisas pistols, 2 1911s and a 5..7 x 28. All are good quality pistols at good reasonable prices.

The Tisas Duty Builders Kits in .45 ACP are of good quality and just a good experience to learn the working parts of the 1911 platform. Once cerakoted and assembled, the pistol performed flawless well with no feeding issues. Don't hesitate to buy these kits when they are available!

Great kit. Easy assembly. Used a small triangular file to trim the front and rear sights for a snug press fit. The mainspring housing pin was extremely snug. Used sand paper to reduce the diameter. After assembly i found the grip safety is lighter than I expected. I ordered a replacement sear spring from Brownells to tighten up the feel. I will again sand the housing pin to improve the fit allowing for installation and removal without the use of a hammer and punch. Fired 50 rounds no problems reasonable offhand accuracy! Thanks for a great product Bob
