1911 Builders Kit Review : What Are Inside The 1911 Pistol Kit?

When it comes to 1911 build kits, there are some components that every good kit should have. These are going to be some of the essential major components you’ll need to either make a complete weapon from scratch or finish off a build that has part of an existing frame already put together. This aspect depends on the exact kit you are looking to buy. 

1911 Frames Kits​

The frame is the general shape of the gun and its outline backbone. This will dictate where the rest of the pieces fit into the weapon together and can affect aspects such as weight, the type of slide and barrels you can mount, and what kind of grip you can put on. It may also affect the calibre of ammunition you can chamber, although this is more related to the gun’s barrel. 


The slide is what frames the next round in the chamber and dumps the used casing onto the ground. Make sure that you get a good slider that will not jam or fail as you’re trying to squeeze off rounds. The slider also needs to fit onto your frame really well too. 


This will disturb the calibre of bullets you can use, as well as their general accuracy and speed. Some barrels are threaded or have other adjustments to make the bullets spin, maintaining their accuracy over lengthier distances. You’ll definitely want to look for a good barrel for your kit though. 

Other Miscellaneous Parts​ 

Beyond those 3 components, check for triggers, grips, pins, and the many screws you’ll need to complete a full 1911 or all of the development remaining for a build that you’ve already started. Some kits come with some extras or attachments, too, and these can be great snips if you were in the market for that particular accessory anyway. 

How to Choose The Best 1911 Build Kit

Before we look at the best 1911 build kits, let’s go over a few important factors to watch for that can help you regulate when a particular build kit is worth your time. 

Pistol Use​ 

Figure out what you intend to use the pistol for. Concealed carry? Government model? Whatever your reasons are, different kits will be better at making diverse variants of a 1911 pistol. Knowing which one you’re going for right at the start will prevent you from making any stupid mistakes or buying the wrong build kit. 


It’s significant that you buy a good kit, even if it’s a little more expensive or out of your budget or price point items frame. You wouldn’t want to make a 1911 out of cheap frame parts. The worst-case scenario is that you may end up building a damaged 1911 AR 15 weapon that breaks or explodes when you try to produce a frame fire. Don’t buy cheap ones! Buy something that is made with high-quality care. At the same time, you don’t have to go for the most expensive kits if you know a cheaper tool that is made with equally good stock quality frame materials. 

Check Your Tools 

Any 1911 build kit is going to need productivity tools, but different kits will have different product parts in numerous stages of completion. Try to find a 1911 kit frame that only requires the tools you have in your workshop. If you have everything you can imagine in your garage and can finish any build, you don’t need to fret much about the kits aspect frame so much.

This is another build parts kit that’ll fit really well on your existing Sig Sauer model or if you’re trying to compete with a similar firearm.

This will allow the various pieces to be installed easily and for a long lifetime of high performance. 

Critically, this kit has a handy extractor pin for removing screws or pins for when you need to make adjustments or if you have to backtrack in your build at any point of construction. We really like this extra bit of functionality and versatility. 

The pieces are all very affordable and within budget range, but they are not a full kit. That means this relies on you having some, or most of the other parts kits already combined or purchased.
