I know this firearm is on the MD list as approved, but only with 10 rnd magazines. Is this available with 10 round magazines here? Is this available in FDE?

Buds does not have the 10rd Model available Jeffrey. I would contact Sig for a stocking Dealer at Phone: 603.610.3000, option 1 Hours: Monday-Friday: 8:30am – 6pm EST

even this model is not listed on the Sig website and I could not find a 10 round version anywhere on the web I suggest you give Sig a call and see if they are being made with the 10 round mag and in FDE Phone: 603-610-3000

I’m looking at the cash price Sig MPX 8 inch for $1407. There are other Sig MPX models that are several hundred dollars more. What differences justify the different price?

Hi Steve, there are no significant differences. This is strictly a stock level scenario. When more of similar firearms are in stock the price could be a few hundred less than a model that is low in stock or near sold out. At Buds the more in stock the lower the price and vce versa.

there are no real differences. This is strictly a stock level scenario. When more of similar firearms are in stock the price could be a few hundred less than a model that is low in stock or near sold out. At Buds the more in stock the lower the price and vce versa

Please click the green box stating it as the best answer. We are rated on our answers and are just volunteers, not Buds employees. You can choose more then one Thank you!

Hi Steve, there are no differences. Price is due to the stock levels. Buds uses an automatic inventory price update engine that runs every 20mins. Prices are tied directly to stock levels and will change as stock numbers change. As inventory numbers go down, prices go up and vice-versa. Usually when popular items get low in stock.

I love this gun. I use it to shoot PCC at USPSA matches. If you are on a budget this may not be a good choice. You will have $2500 or more in it by the time you get all the extras for it. Having a locking bolt is a nice feature that insures you will not have an out of battery discharge that one sometimes has with a blow back action.

Great 9mm sub-gun/pistol. Ambidextrous controls are excellent after getting used to. Comes with 1 mag, I recommend a couple of extras. Will require your choice of optic or iron sight. Very milspec trigger, although a Timney drop-in is available. Fun shooter out of the box, and at this price for the base model, allows you to spend money on the upgrades you want as opposed to ending up with random spare parts. Buds was great from start to finish. I will definitely be using them again and again.

Awesome gun. Fun to shoot. Nice quality. Buds again with the quick shipping and excellent service

Excellent purchase. Delivered quickly and as advertised. This is my 8th purchase from Buds and due to the political climate and the renewed push to shred the Constitution, I will be buying more from Buds.

Great gun, better then the newer Gen 2. I highly recommend getting SBR’d though.

Jerald A on 08/22/2017

Excellent, high quality firearm. It was designed by Sig as a submachine gun so it is very tough and robust. I am happy they made this semi-auto version that we can own. So far I have added a SB TACTICAL brace, A.R.M.S BUIS, Sig Remeo 4C red dot sight and two additional 30 round mags. As soon as I can afford it I will add a Sig suppressor. In the short time I have had it I have put a little over 600 rounds through it with no malfunctions of any kind. Perfect example of "you get what you pay for".

Just got my mpx from my ffl yesterday. Threw on a new eotech and sent in form 1. It is awesome well made. And worth the the price. Shoots great. I love it. Buds was fast with shipping and I cant wait to find something else to order.

Buds does some special deals with the price matching. Feel lucky to have got in at the right time on an awesome piece. The MPX is already got the Tax Stamp applied to make an SBR. Can't wait.

Thanks for fast shipping buds guns. Great firearm. This is my new favorite gun. 200rds no malfunctions. Shoots smooth. Only complaint is the price of the magazines. Highly recommended.
