Colt 1911 Rail Gun Build Pt. 4 – Finishing it up

We’re in the home stretch with the Colt 1911 Rail Gun build now, time to finish up the trigger install and respray the gun. 

See part 3 of this build HERE

One more screw and pin and the whole firing assembly will slide out the top of the frame. With this clear, you can remove the trigger unit out the back of the frame, through the grip safety hole. There’s a small spring on top of the trigger that you’ll need to remove before taking it out of the gun. This spring will not be used with the new trigger.

The trigger unit in all it’s naked glory. That small nub on top pushes back against the spring removed in the last step. The trigger pushes against the sear spring, so I don’t feel this secondary spring is necessary. Tap that small pin out and you can remove the trigger shoe from the trigger linkage.

The 5KU trigger we went with is adjustable for overtravel and has a flat face for improved trigger feel. The skeletonized finish looks amazing as well, and fits with the classy look we were shooting for. The trigger linkage needed a tiny bit of sanding to fit the new trigger, but the install was otherwise painless.

While the frame is empty, I took some time to prep and paint it to match the compensator. Unfortunately, I ran out of paint, as this build was kind of a tragic comedy at times, and had to go with a different color that doesn’t quite match. It’s close enough for now.

The frame under the lights. Not a perfect finish, but it works for now. Eventually, this whole gun will be media blasted or cerakoted or something else awesome.

The trigger installed easily and the rest of the lower components went in with a bit of trial and error. Pay attention to the way the sear, sear spring, and main spring fit together to make reassembly an easier process.

33

Reassembly was a breeze, just screwing the grip panels back on the frame and putting the slide back on top. Some final lube to keep things running smoothly and the gun shoots like a dream.

One thing I’m in love with on this gun are the smooth wood grips. It’s amazing how something so inexpensive, with a little bit of TLC can totally change the personality of a gun. If you have one of these 1911s by Cybergun or Elite Force, you should absolutely consider modding some real wood grips to fit.

You can see the notches in the grip panels that were dremeled out to fit the humps in the frame. You can also see how the second panel (top) is much cleaner than the first one I did (lower). You can also see where I ran out of paint while painting the mainspring plug…

One more glamour shot, because this thing is quite pretty. The paint finish is the main thing I’m not 100% about, but I’ll be fixing that in a later article.

WRAP-UP

So there you have it, for under $50 but with a bit of elbow grease, you can totally change the looks and personality of your pistol and class things up a bit. The flat faced trigger, once properly adjusted, vastly improves the trigger feel as well as the reset for quick follow up shots. The compensator adds a bit of weight to the front of the gun which helps the overall balance, but is otherwise a purely cosmetic feature. The biggest change to this are those grips though. 1911s really look great with real wood grips, especially ones with a smooth finish like these. The real 1911 market is flush with options for grips, and now that you know how to modify them for CO2 pistols like this, the sky is the limit for what you guys can pull off. So go forth, Dremel tool in hand, and make 1911s great again.
