Thunder Mountain STI Spartan Delux Package
(Yep, we misspelled it on purpose)
This is the West and we can do that



STI Spartan Delux Package Deal
We've taken one of the greatest 1911 deals ever available or manufactured and improved on it for the better. The Spartan Delux (Yep, we misspelled it on purpose) Package is set up with the Thunder Mountain Excusive "STI Logo'ed Aluma Grips" you can't get these from anyplace else. They provide a lifetime of service without any wear or tear. Then we install a new mainspring housing and magwell, change out the main spring and sear spring, Plus we add in a 40" length of the brightest fiber available (Just look at the ends of the fiber in the picture), there's no brighter fiber available, period... (we have it made just for us). Then we took an additional step and added a US made MilSpec magazine to the package. Like they use to say in the movies "Holy Cows Batman, that's a smoking DEAL"
New projects and products are based on customer demand and feedback on current products that are available on the market, many of which we offer and for products where a quality product is lacking. We have no problem with offering you a product that is produced by another company as long as it's a great product and priced right. We listen to our customers, and if you have an idea for a new product or for one that needs to be improved on, we want to hear it. Thunder Mountain always wants to provide the best parts, pieces and firearms to the shooting public. If you have a recommendation on how to improve a product that we offer or for a product that does not exists, then the chances are that someone else is thinking about the same thing, so just let us know you can email your thoughts and ideas to
Although we manufacture many of the great parts that we offer in house. We have a great group of partners that we work with closely all the time to produce parts that exceed our current manufacturing capabilities. All of our parts and accessories are made in the USA. We do not offer substandard off shore produced products and never will, and we would not even think of the thought of offering them to you, we know you need reliable parts and products not only for Competition but also for your personal security and protection needs.
The upcoming products listed below are based on demands that we have received from you, our customers.
All of the project listed below are already in production or in the prototyping stages. As we get them completed and ready for shipping we will move to the upper portion of this page and will be adding new projects as we complete the projects listed below
1911's
We still believe that a custom 1911 should be just that. When your paying top dollar for a custom 1911 you should get a Custom 1911, and not one that looks like everyone else's gun at the range. So on our customs 1911's they will remain just that, total customs, with no two ever built or looking the same, only built the way you want it and of course with an average 8 month lead time. But we have realized there are a few voids in the 1911 market and we have gotten enough request for next two new products that will be offer soon.
The first two projects, Although not custom 1911's will have all of the bells and whistles, built on nothing but the best parts available. And will be a total bang for the buck
The First Project
We are going to be doing the Spartan Next Gen (Next Generation). Everything you saw above in the Spartan Delux, PLUS Hard Chroming and Some wild "Thunder Mountain Custom" front strap Stippling at prices that will just amaze you. Pictures will be posted soon
The Second Project
We are going to be doing a 6" 10 MM Hunting pistol. This will be a single stack 1911. They will feature Dawson Tritaum sights to make that early morning or that last shot before dusk count every time. Front straps will be checkered or have an aggressive Thunder Mountain Stippling design, so you will have positive control, on those cold mornings when your in the field when you have to wear gloves, but still enjoyable and not overbearing when your just out at the range shooting. They will be built with a bull barrel to help tame the 10 MM recoil and we are current seeking a toolless guide rod for a 6" 1911, so maintenance in the field if ever needed is easy.
Holster Upgrades
If you run a SafariLand 012 or CR Speed Holster, we have new barrel support for you. As normal, Engineered in the Thunder Mountain way. Your gun will never leave the holster unless you want it to, and built of only the best materials available, no plastic parts on these, there's nothing that will break during a match. The fist production run for the SafariLand 012 holsters has been completed, and we are just waiting for the parts to come back from the Anodizing shop The CR Speed upgrades will be available shortly.
Slide Rackers
Race gun guys, We have an new Slide Racker coming out. This one is totally different. Not built on a casting. This one is built out of SOLID barstock, and totally functional and has features to provide positive control
MAG WELL's
We have been looking at the current designs for the past year or so, and there are some better solutions. Some of the MagWells out there like the Dawson ICE Magwell are as perfect as it can get for 90 percent of the shooters and we stock them and use them on all of our custom guns and Totally Tuned Edges. For the other 10 Percent we will be offering MagWells for those of you with smaller hands, larger hands, and those of you that would like to have a MagWell that is narrower in general, but still offering a larger pocket.
Fire Control (Hammers, Sears and Disconnectors)
We have finally found a manufacture who is able to produce our new line of light weight hammers, sears, and disconnectors, at the quality that we want for our customers. We just received the first lot of prototypes, and need to run them for a few months, before we start production on them, just to make sure everything is perfect. All of the internal parts will be Rockwell harden to C51-53, which will result in a trigger pull that does not change, no matter how many rounds you put through your gun. These will be pretty much a drop in trigger job, with no additional stoning required
